Refilling Propane on the road?

I border on control freak, so I definitely want my own tanks. Looking on the net, some of the major propane distributors have some good online maps to refill places. I'll just have to set up a quick reference navigation log for each trip, I'm going to need to know which exits have restrooms anyhow...ain't middle age grand!

OK, good to know. Sounds like there is no need for me to add a second tank this year. We are going to be going to the cottage in the colder weather this year, but that will be in very easy access to propane since it is a typically highly populated beach area. I will worry more about battery life during my learning curve.

Thanks for the info here. We are just about ready to purchase our Rpod and I was considering dual 20 lb tanks however I already own a new 30 lb tank.
I also own a Mr. Buddy heater but other than battery issues running the furnace, why would I want to run the Mr.Buddy? There is a fair amount of condensation that comes with running one of these.

Tank swaps can be a great convenience. I've never had a seller balk at letting me get a newer tank if they hand me one about to expire.  Those guys really don't give a hoot.  I generally prefer having my tanks refilled because it's almost always more economical, but I'm not going to drive 10 miles out of the way when I'm on vacation to make it happen and it seems kind of silly, to me, to get attached to a propane tank.

And I camp a lot in cold weather.  I've gone through 20 lbs of propane (or whatever is in a full tank) in 2 days.

The onboard furnace is LOUD, so I generally carry a Mr. Heater for some peace and quiet when we don't have hookups, which is most of the time.  Plus, if you do run out of propane for the furnace, you can still stay toasty.  And we use the Mr. Heater in the R-dome or the popup screen house.  (It makes a big difference.)

TT

While the onboard furnace is not quiet, I would not say it is loud, nor that it isn't something you get used to. We ran ours on our trip in December/January and slept quite well. We set up a fan right next to the bed to circulate the heated air better because the vent blows straight out under the bed in the 179. That fan was a constant sound. We also run a white noise app on the phone, which also helps cover the furnace noise. After a night or two, I did not really notice the furnace and slept quite well.

I expect that the air conditioner will be similar. At first, it will seem noisy. After a night or two, it won't bother us as we will get used to it. We will probably continue to use the fan to circulate air. The AC will be used if we have power and the nights are hot and humid, and especially if it is raining also. If it is mild and dry, the windows and Fantastic Fan vent will probably be all that is needed.
