Date Posted: 24 Nov 2016 at 2:45am
 After much noodling I think I came up with an answer to the furnace blowing hot air under the bed and then sucking it back in again while never heating the Pod evenly.
Video link;   http://drive.google.com/file/d/0B_wD1bI-4-mdUVNYUXlKcDJMUDA/view?usp=sharing - http://drive.google.com/file/d/0B_wD1bI-4-mdUVNYUXlKcDJMUDA/view?usp=sharing
 
There is now a template on page 2

I built a 22 gauge sheet metal can with heat reflective shielding that seems to work really well. It lifts off and goes on in seconds. Total cost: $16. 
 I've retained all the return air slots as they keep the unit cool by giving constant airflow down the sides of the furnace. And gave good flow to the small square vent in the bottom corner; which i can only call a very important cooling tunnel. When the furnace is running a good amount of air is pulled in here. I think the furnace actually runs better now only sucking in cool air and it heats the pod way more evenly. The original grill has 48.5 sq in. of opening, and this one has an opening of 5" X 10 1/2" for 52.5 sq in.
 I have seen a few attempts at this in the forum and took a hard look at the unit and think I got it. Let me know if you think I missed anything.
 
 
 I actually ran the cardboard prototype for 10 minutes to see how it worked and it never caught fire!
 
 
 
Here are photos of the process:
The template. This was a puzzle! (the 5 1/2" sides are acually 6")
 Cutting, I used tin snips and a cutting wheel.
I don't have a pic of the 2 large bends, but I used a 1x6 screwed to the work bench with the metal sandwiched between it, and just bent it up. Smaller bends were done with a block of wood.
  
For small bends and seaming I used these:
 I used a pop rivet tool for all attachments.
I added curved pieces for less turbulence.
I then finished all the cuts that go around the furnace grill and covered it with heat sheild heat reflective tape.  I just realized the bottom return air isn't needed as the furnace sits and mounts to the plywood cabinet.
Did take 3 hours of playtime,(half of that was drawing the templet), I think a shop could do it 1. I'll ask my local guys what they would charge and let you know. 
Cheers! John

Make that 2 !  If you aren't going into production, guess I will have to copy your idea and make one.  Looks great.  Thanks for sharing.

I think you covered the essentials of having the return air free. That was the problem with some others I saw. This looks good, and I will be thinking of using your example also. Thank you for posting it.
Do you have a sheet metal brake that you used to make the bends in the sheet metal? If not, what did you use?

I think the only thing I would make sure of is that the area of the air output of your duct is equal to the area of the output on the grill so that there is no restriction in air flow.

Stephan,
 I saw your thoughts  in another link on the deflectors some built and thought , "challenge excepted"! 
The furnace grill openings are 48 sq inches and the front facing opening on this one is 52.5 sq inches (5"X10.5"). 
No break, I used a square edge 1 x 6 screwed to my work bench flush with the front edge. with the metal under it for the large 2 bends and these for the small bends, I'll add a few more pictures to the op.

Stephan,
My sheet metal guy says 1/2 hour labor ($47) and $8 materials for a total of $55 plus tax, So $60 ish. This does not include the frost king wrap I got at Home Depot($11)  If I did 10 of them it would drop the price of each one by 20%. He thinks it's a perfectly good design and wouldn't change a thing,(Yay, me!).

MichelleC,
Looks like the heater is under the queen in the rear on the slideout side, so now we need right and left hand version, to make them work right, shouldn't change the cost. I guess I don't mind if enough people are interested, or someone on this forum must be a tin knocker, either now or in a past life, Wanna make some money and be a hero and make people love you,and get Karma?...../
 
 So +1 right facing.

Unfortunately, that is a bit steep. I guess $47/half-hour is not unheard of, but it is not going to fly right now. Even 20% off, still leaves the basic metal (without the wrap) at $44 plus shipping.

If you could make a full-size template on something like kraft paper, it would be easy to put that into an envelope. How much would you want for that? I have the tools to cut and bend the metal myself (tin snips, vice, boards, rubber hammer, etc).

Stephan,
No problem on a template, I'll make one next week and just send it to you.
Anyone else wanting in let me know.
 I'm wondering if I could just make a PDF on autocad and make a link you (and others) could print at a print shop? I'll pm for your address when it's done, I wouldn't pay that much either but a few tools, desire, a little blood goes along way.

Thank you. I appreciate it. I'm not familiar with Autocad, but PDF files are easy to work with.

We have a Staples near us and I believe they have a large-format printer. I can call them and ask if that would be something they could print for me.

If the template can be split to print on multiple pages with registration marks for alignment, I have an HP OfficeJet 7610 that can take up to 11"x17" (tabloid) paper and tape the sheets together  for a larger template. That could also work for 8-1/2"x11" paper. It would just take more sheets.

Stephan,
 I put together PDF's of the deflector. I also did a top, side, bottom and front in PDF form. If you need it in PDF form, Pm me your Email and I'll send them. Couldn't scale them full size but you should be able to use the #s. These are the corrected drawings with minor changes.

The numbers on the top cuts for the bend taps and return air don't add up. You should just use your grill and mark it how it should be until i have time to change the #s


The foil wrap I used is from Home Depot, Frost king-foil wrapped foam, in the sheet metal section. Good luck and have fun!

Thank you. That is great!  The numbers on the smaller size drawing will work fine. What did you use for sheet metal? Was it an aluminum sheet or did you use a galvanized sheet? I'll use these patterns to work on a full-size template so I can see how the parts fit together before marking and cutting sheet metal. I appreciate your making this available.

Do you think this would work? https://www.lowes.com/pd/The-Hillman-Group-24-in-x-2-ft-Plated-Steel-Sheet-Metal/3054565 - The Hillman Group 24-In x 2-ft Plated Steel Sheet Metal ? It is 26 gauge. I have not been able to find 22 gauge in the size that would fit the template measurements at a reasonable price. There is also the https://www.lowes.com/pd/IMPERIAL-24-in-x-3-ft-Sheet-Metal/3234805 - IMPERIAL 24-in x 3-ft sheet metal , but it has in the specifications that it is 30 gauge

Stephan,
 I used 22 gauge because that was the size of the scrap piece my sheet metal guy had on the shelf cheap.
Home depot sells a 24 gauge 24" x 24" for about $10 that would work fine. 26 gauge is fine also.
I made few  changes,
 1. I deleted the return air slots on the bottom because the furnace sits right on the plywood and it did  nothing.
 2. Made the shortside back piece a separate L shaped piece because it's one less seam in an awkward corner and made the tab overlaps easier, and it made the template a little more sane.

Thank you. I look forward to making one of these. I'll look for the 24 gauge sheet the next time I go to HD.

With John's plans, I was able to get a deflector made and installed in our 2017 179.  Thank you John for all of the insight and hard work in getting the prototype and plans developed.  For those of you making this, make sure your bends are good, I did not have a brake and was in a hurry and it threw my measurements off.

How hard would it be to just remove the furnace ?  We live in MS and never need heat in an RV and we never go north when it's cold. Could you convert the furnace area to useable space? 


Posted By: voisj
Date Posted: 02 Jul 2017 at 10:32pm
Datsmar,
Anything is possible. Not sure if the gain is worth it though. Here's a picture of what is under the plywood. you could gain a 18" wide space or so. You can see the water filler pipe in the picture that would limit the space available. (if it's a 180 or 179)

You would need to find a storage door or something to waterproof the opening in the side of the pod left from the removal and for access from the outside and/or a mod to the cabinet for storage access from the inside. like this tub set up I did on the opposite side,


There are pipes and wires that would need to be moved and/or re-routed, or the floor space covered with a false bottom to run the pipes and wires, and a cap on the gas line. So it's definitely do-able.

Thanks for all the great ideas and research here. Any thoughts on adding a drawer after this mod. If you made the drawer with notched corner where the heater is (I've seen a few mods showing this) would you get enough cold air return. I really need to add some drawers. R-pod 178 had such little storage. 

Thanks. I

Dherman,
It could actually be done!
If you left 3" from the edge of the can to the drawer,plus the space above and below the can,for return air you would have enough sq inches of return air to almost double the return air needs.
Not sure if you can raise the mattress and put drawers under http://www.rpod-owners.com/forum_posts.asp?TID=9039&title=2nd-180-podmod-drawers-under-matress - LIKE THIS  Due to the sloping ceiling, but it's worth a look.

I think the furnace deflector is a great idea.

But......

What I did to NOT have to use the furnace with it's battery-sucking fan (and be able to boondock, or camp out in the boonies) is buy and install a Wave 3 propane heater.  It works great and uses no electricity.
One could even buy the larger Wave 6 heater.

Just a suggestion for an alternate solution.

Geewizard,
I like the concept, silent and the reviews are solid. I assume radient heat?,says no flame? How does it heat?
Advertised as a RV heater but says "ventilated areas only. Are the minor burned propane fumes dangerous at all? (Carbon monoxide). Doing research now!

Marwayne,
I like this idea! How well does it heat the Pod? and did you remove the furnace? (thinking outside or inside storage).
Since I did the twin bed mod I could put it in the nightstand and it would blow straight down the length of the pod, and would be less than a foot from the water heater.
How does the thermostat fire the pump, with a relay?

The Wave heaters use a platinum catalyst for the propane.  They are radiant heaters with no flame.  A number of users including me crack a window or vent for fresh air per the instructions.

Everything is dangerous.

Yes, I am still interested as well. It would be good to find out how much they would cost to build. That always seems to be the sticking point.

Just got a 2016 180 and love your mods! Big fan of the heater mod and keypad on the door. I was curious if you ever made additional units or found a source for purchase as I don't believe I'm personally handy enough. Id also love to know where you got the keypad from as well and how difficult the install was. I'm also shopping for batteries and am curios as to what your setup consists of. Thanks for your time.

I thought I was not handy enough either, but it reached the point where I either made it or reconciled myself to doing without. I made it and while it was a challenge, I'm glad I made it. It works great.

As for the keypad, it is from Bauer. I did not install it. It was installed for me, but iI watched, and it really is simple.

As always, check other sources to see if you can find a better price. The batteries last a long time. I finally had to change them.  As for the battery setup, if you follow the links, you will find the most current pricing. I did the work myself and that saved a lot. If I had someone else install the battery, the charger, and the wiring, it would have cost probably double. I got it done the way I wanted instead of the way someone else might have done it also. I don't like paying to have something done and then having to redo it because it was not done the way I thought it should have been done.

I thought about a heater deflector for my 179 but concluded it was not needed. Heat rises by natural convection. The opening under the bed for air to move in and out is more than big enough to circuiate heat from the 20K btu/hr furnace simply by natural convection with no forced convection at all, and of course the fan does move some air.  It will get roughly 20-30 degrees hotter under there than in the rest of the trailer at which point the temps will equalize and the full furnace output will go to heating the trailer. It only takes a short time for the temp to rise under there. Just don't block off the opening and it works fine.

OTOH, I like that the heat is now coming out into the trailer and the rest of the space remains cool. I could conceivably use that space. As it is, I have my DC to DC charger in that space and I don't think having the furnace blowing directly on it would be good for it. For me, the deflector is functional, practical, and necessary. My needs and situation do not apply for everyone though.

I just wanted to point out that the deflector doesn't really make the furnace more efficient or heat the trailer any better. 

I agree that without a deflector the space under the bed will be warmer than the rest of the trailer, so for some that could be a disadvantage. For myself, I like that space being warmer. If its wet out I can put my boots or other wet stuff under there and it will dry overnight. Might be a bit stinky though Cry

Yah. I prefer that the stuff under the bed not get heated. I would imagine that heat gets into the air of the trailer faster with the deflector.

Faster by a minute or two when first running the furnace but not more efficient over time. Might even be more efficient to heat via warming the area under the bed because that will allow the furnace to operate on a slower duty cycle. Short cycling kills efficiency plus the fan coming on and off is annoying.  I keep some bottled drinking water under there which adds thermal mass to retain heat and likely slows down the duty cycle even more, although I haven't tested that.

Stephan,
 What DC to DC charger do you have? I just got a dometic elec cooler and added a battery under the truck shell in my bed and would like it to charge while driving.

This is the one I have:  https://www.renogy.com/12v-dc-to-dc-on-board-battery-charger/ - https://www.renogy.com/12v-dc-to-dc-on-board-battery-charger/
There is a 15% off coupon listed on the site. How long that will last is a question. I also added a dedicated charging circuit with a battery isolator relay to power it. If the battery you put in the bed of your truck is the same type as your truck's battery (e.g. flooded Pb-Acid or AGM), then you could just put in a battery isolator circuit. You would not need the DC to DC charger. The battery isolator will prevent the cooler from running down the vehicle's start battery when the engine is off. I needed the charger because the charging requirements for LiFePO4 are different than for flooded or AGM Pb-Acid batteries. Check out this search on Amazon for some ideas of what is available.

Stephan,
 I did set it up first with a battery isolator, But when driving and charging the second battery when it was low and running the cooler my truck (2013 F150) display throws an electrical overcurrent error code.  The truck has SOC sensors that have to be disconnected to kill the code but then the check engine light stays on

I have an optima agm for my main truck battery, and a napa legend agm for the second. I'm told a 12v to 12v charger does the job. Thanks for the recommendation.

Be sure to get a boost dc/dc converter, not a buck converter. But you might still get the charging overcurrent error code, indeed you might get it more frequently because you could end up charging the second battery faster than before. There are two ways to prevent that, one of which you can try with your existing isolator setup. 


Option 1: reduce the gauge of the conductors running to the second battery. That will limit the current that can flow through that circuit. Of course, you will need to have the appropriate fuse in the circuit to protect the smaller wire. 10 gauge might be a good choice. 

Option2: Try to find out what the current limit is that triggers the code and where that is being measured, and get a dc/dc converter that is rated less than that, or less than the total of that plus the tow vehicle current demand if the current is being measured at the alternator output. You might want to pick up a dc clamp on ammeter if you don;t have one already.

I had not noticed any errors with the Frontier. On mine, the wire goes direct from the positive battery post to the solenoid, and then to the back connector. The trigger wire goes from the fuse box under the hood to the activator connection and then the ground for that goes to where I saw other wires connected for ground. I hear it trip on when I start the Frontier and trip off when I stop it. I hope you get it figured out.

I second the suggestion for a clamp--on meter. I have the Southwire 21050T AC/DC TRMS Clamp Meter. I chose this model because it can read both AC and DC Amperes. It was also reasonable in price.

It sounded to me like the F150 error was for excessively high alternator current. 

Here's a multimeter that looks like it can do it all, including temp, non contact voltage, and capacitance as well as ac and dc current. Professionally I always used meters from high end companies like Fluke and they were robust and reliable for constant use. But for RV and homeowners' very occasional usage I think the new inexpensive Chinese meters offer a great value and work fine.

 All dc current clamp on meters work via the Hall effect and tend to drift and be susceptible to stray magnetic fields, so its best to find an isolated location when you can clamp on the meter, zero it, and then leave it alone for the duration of your testing.

If you're looking for a clamp-on ammeter, be sure you get one that can measure DC current, which up until a decade or so ago was not the norm. Measuring DC current requires a somewhat special Hall effect measuring device. In times past (not exactly the old days, but I digress) clamp on meters could only measure AC current.

I picked this one up at Home Depot. A bit more expensive, but I consider Klein a good brand.

https://www.homedepot.com/p/Klein-Tools-400-Amp-AC-DC-Digital-Clamp-Meter-Auto-Ranging-CL390/312649921 - https://www.homedepot.com/p/Klein-Tools-400-Amp-AC-DC-Digital-Clamp-Meter-Auto-Ranging-CL390/312649921

I also have a Fluke meter, but it doesn't have a clamp on ammeter.

I have had other "cheap" meters in the past, and while they usually work, there have always been some kind of issue with them.

Thanks for the ideas Steph & OG & GG

Plan to tackle this one today, Going to try a smaller wire first, for this trip, Didn't even think of that, I used #2 wire That came with a winch package. the guys on the overlander forum all use dc to dc chargers, with separate battery banks, so thats my end goal... when I get back east.

I also use this truck as a off grid overlander and I have way to much stuff on the starting battery, (12,000lb winch, 2000w inverter, the dometic cooler, On board air compressor, big LED lights all the way around, And usb/leds/12v ports by the bed in the shell camper, Going into Canyonlands NP backcountry later this week on my way to the east coast,(no rpod this run)

GG, I have the Klien clamp meter, but it's  currently on the east coast and I'm on the west coast, My daily carry is a Fluke model 73, 25 years and still doing the job!

OG, Yes it was overcurrent protection, charging the 2nd battery and running the cooler. I have a 240amp alternator so there is plenty of current, The truck just thinks something is wrong and insists on letting me know.
And the deflector works surprisingly well, with the only drawback (on a 180) is the airflow is directed straight at the thermostat , (ten feet away) and it did cycle the furnace off and on a bit more, not alot ,but a bit... But the gain of not heating the now usable for anything space under the bed was worth it,(to me).

 Kickhead70, Try the bread pan idea, just cut off one side and screw it to the grill over the front 2 grills. this allows for the cooling vent on the grill to be free and also a bit of heat under the bed.

voisj, do you know what criteria the vehicle is using to throw the overcurrent error code? I wonder if its using a fixed current level from the alt or something else. Alts are rated while spinning at a pretty high rpm, I believe its 6000 rpm,  their output is much lower at idle. 

So it could be the overcurrent criteria varies with rpm or is based on alt temp (an alt will overheat at lower current at lower rpm because its cooling is reduced). If you really want to be able to run all that stuff at idle then you might want to look into a custom alternator, they are readily available from companies supplying the auto audio guys.  A DC/DC converter will limit the amount of charging current to the second battery but the actual total current available will go down (because of converter inefficiency) not up.

OG,
The Battery cables have rings floating off the battery wires about 3" from the battery. the alt is a 240 amp unit and back in the day just adding a battery would be fine, but todays vehicles sensor and monitor everything. And overworking an alt creates the heat and you mentioned and reduces the life.
The DC/DC charger Charges while driving and has solar ports for if I'm idle. and shuts off if the starting battery goes below 11.9v. 
 I have a 100w briefcase sized folding panels for when I'm idle all day. (Rockpals,com)

Seeing as how I'll never use everything at once, Never used even 1/2, and the second battery will mostly be used for led lights in the shell and the Dometic cooler, only while truck camping off grid, As I usually Travel during the day,  I like this solution.

 The CFX55 IM cooler is a marvel, has been running on the AGM battery with no charging for 40 Hours. (still testing ) Has been averaging 1.1 AH/H on 12v ( per the app that monitors it) Peak amps 3.7 when it kicks on and then 2.0 while running, .2 while idle. And shuts itself down at differing voltages per user set battery/voltage settings. And even has an icemaker!! Downside is it's $$$$.
Have to thank user Crazycoyote ( another 180 mod nut) who I ran into in a forest near Flagstaff AZ for letting me know I needed This).
Didn't mean to hijack the topic but, Thanks for all the of topic input!!
John

So the vehicle is monitoring two hall effect donuts located on the battery cables. Interesting that Ford is measuring the current in both + and - conductors, the current should always be the same. Redundancy probably. 

When does the error code show up? Presumably the battery discharge current is ignored while the starter is operating as that is several hundred amps. 

Anyhow, my guess is that the over current condition only lasts a pretty short while when the second battery has seen some significant discharge prior to energizing the battery isolator to connect them. After a short time the battery voltages will begin to equalize and the current will drop.  

Anything that limits that initial current flow should solve the problem. Either a sufficient length of smaller gauge wire or a dc/dc converter will do that. I'd suggest about 20 feet (one way) of 10 gauge to bring the max current down. Or for $6 you could leave the cables you have and install two of these in parallel and do pretty much the same thing:

https://www.amazon.com/Cutequeen-Aluminum-Wirewound-Chassis-Resistor/dp/B01MT69M5K/ref=sr_1_3?dchild=1&keywords=0.1+ohm+resistor+100+watt&qid=1605707026&sr=8-3

The Dometic fridge you have looks like it uses the tried and true Danfoss/Secop compressor. Should be a good unit for you as long as you have the 25-30 AH per day power source available. A 100 watt solar module would more or less do it on a sunny day.

Colt asked me to post a picture of my bread pan heat deflector when I had a chance.
I liked this idea because i could position the pan to leave the cooling tunnel vent (bottom)and small upper rear heating vent (upper) of the grill unobstructed, letting a little heat blow under the bed.
 The size of the pan works good, the air is diffused with a fan type flow. And works well
I tested it for an hour and no issues. ( it's22 degrees outside right now.)
I bought a $3 bread pan at The Dollar store and cut 1 side and screwed it to the furnace grill
I used a $3 auto zone door trim to cover the sharp edge. so $6 and 20 minutes.
Also a picture of the angle iron replacing the 3" piece of wood  under the bed to open the space up for ease of use and let heat out better if you don't have a deflector.
