Heating basement in the winter

Cheap Heat has some very specific requirements and high amperage requirements. You need 50 amp service at a minimum and some special wiring is required.
If you use electric heat inside, you can also use electric heat outside. We use a couple of 100W light bulbs in the wet bay and where any plumbing exists. There are also some really nice, really small 250W electric heaters that will do the job and circulate the air as well. If you plan on "seriously cold" camping you might need the propane and the electric heat to keep your plumbing safe but in most 20's - 30's camping, most class A's will do just find with a bit of supplemental heat.

If I had room I would install Cheap Heat which is basically an electric heating add-on which uses your duct work.

Just came back from the West. The winter-overers use that extra cylinder outside with an isolating valve and regulator to the main utility line. Just make sure your connections are outside any compartment and has fresh air.
Newer units direct heated air through ducting. Ne-e-e-ver use heat tape=majority of fires (hillbilly Ahia chronicles)

It looks like the average daily lows are not much below freezing and the average daily highs are well above freezing year round in Pigeon Forge. Much of the time you probably would not need to do anything to prevent freezing of tanks in enclosed basement compartments, doubly so if the RV is generally heated in some fashion or another. I suspect (but do not know) that the pipes are all inside the insulated portion of the RV, rather than being outside or in the basement area; that's generally the case for RVs that are set up to be usable in freezing weather.

According to the specs I see online, a 2014 Tiffen Allegro Red 38 QRA has a 24 gallon propane tank, or around 80 pounds usable capacity.

Hi ssands,

I replaced the return air grill for the furnace with a dual window fan. It is thermostatically controlled (add on thermostat) and pushes some air through the duct work in my class C. https://www.walmart.com/ip/Holmes-HAWF2021-WMUM-Dual-Blade-Twin-Window-Fan/17133777

We can use electric inside the coach but I worry about keeping the basement warm enough to keep the pipes from freezing.

You can use light bulbs, If you can find the short oil fil heater that also works. If you have a taller bin then the regular size will work. Our 99 had a switch that you turned on to heat the basement. It was just a blower motor like use on boats to suck warm air from the duct and blow thru the basement area.
