    Posted: 30 Aug 2013 at 11:31am

I am looking to purchase a generator to have power deep into the mountains while camping.  What specifications should I be looking for to power our new 182G?  Willl the "Generac GP 3,250-Watt Gasoline Powered Portable Generator" be a good fit?  Thanks so much for the asssitance and recommendations.

The size is right but there are a few other considerations.  If you plan to stay in campgrounds, it will probably be too loud.  If that is not a problem, how will you transport a generator that size?  Is it too heavy to move easily when you are ready to set it up? 

These are but a few of the things to consider.

I never considered the noise - are there any recommendations for a generator?  I have seen a Honda on a few posts...what should I be looking for with respect to power requirements?  I am so new to all of this!

High up in the mountains a Honda 2000 would suffice since you would not need air conditioning. Yamaha also makes a nice small rv geny

I'll add one more consideration - fuel consumption.  This gets tied directly into the noise issue with modern generators, because there are 2 types of generator.
 
Standard old-school generator - runs at full speed (3600 rpm) all the time, loud, and sucks down gas even if you are just charging a cell phone.
 
Modern "inverter generator" - the electric is actually produced by an inverter, which allows the engine to idle down to a low speed when there is a light load.  This also usually means they don't have to rev up to 3600 rpm at full load.  Most also are designed with soundproofing, so for all these reasons they are much quieter even at their highest speed.  They also use much less gas especially at lower loads.  Honda and Yamaha are the two best manufacturers in this division.
 
There are many others out there now in the inverter generator market, but none match the red or blue brands in the sound department and most aren't built to last as long (on another forum I read of a Honda that lasted 5000 hours).  The benefit of the "off brands" is they are also much cheaper for nearly the same benefits over the shorter term.
 
If you will never use your A/C or microwave you would get by with a 1000 watt generator w/o a problem.  Basically you would just be recharging your pod battery every few days, and running/charging other low-wattage stuff.
 
If you need to run your microwave or A/C you get into a grayer area.  To run both at the same time you would need a 3600 watt generator and even that wouldn't work if both started at the same time (compressor and microwave).  If you ensure you only run one or the other, you can get by with a 3000 watt generator and be pretty much guaranteed it will run it no matter where you are.  Just turn off the A/C for a few minutes while you heat up food, then turn it back on. 
 
You may be able to get by with a smaller generator, around 2500 watts, to run either/or but this is where it gets even grayer.  The higher you are in altitude the less power you get from a gas engine - so less electric can be generated.  Also the hotter it is the less power you get from a gas engine - so less electric - plus the double-problem that A/C compressors are harder to start the hotter it is.  And some of the pods have 13,500 BTU A/Cs while others have 11,000 BTU A/Cs.  The larger A/Cs may not always start when its hot out with only 2500 watts....
 
Our pod has one of the 11,000 BTU A/Cs, and I have an inverter generator 2400 watt Yamaha.  it burns 1.6 gallons in exactly 8 hours while running the A/C, converter, and charging our phones and computers, overnight.  So far it has always started the A/C even with temps into the low 90's.  If we had the larger A/C I wouldn't feel so confident with the same generator.

Excellent explanation Doug.  We have the 13.5 a/c.  I couldn't lift the Honda 3000 so ended up getting two of the 2000i's.  I can load either or both, depending on whether I will need the A/C.  You can't go wrong with either the blue or red guys.

The blue and the red generators are the two time-proven brands of inverters.  There are a few new kids on the block that are less expensive but are so new that their long-term durability and longevity are unknown.  I am thinking of the Dometic LW3000 and the 2600 watt unit that Ryobi has out. 

I have the Dometic, but it is too soon for me to comment on how it will hold up.  Short term, it has been great. I might add that I am not very fond of Dometic products but I decided to take a gamble on this one.  If you don't care to gamble, go with either the red or the blue.

I have  a 3000 watt generator.  I can run the Microwave and AC at the same time. A third high draw item (like say my wifes hard driyer LOL) and it will stall the Generator.

The Red inverter 2000i (Honda) has a fuel pump and a small outboard motor gas tank will run it all night. The Blue (Yamaha) does not have the fuel pump so what the tank holds is what you get. Not fun to get up at 2:00am to refuel the gen so you can have heat.

I'm working on that problem.  Gravity is an asset.  Clown

But definitely the red gensets are easier to extend the run-time with out-of-the-box solutions.
