I believe the L.P. tank is 10 gallons as well, but I have no idea if it is full or empty.
That may run the furnace for less than 48 hours in the worst of the winter.

If it's a harsh winter than I may not be able to get my motorhome out to refill tanks, unless the tanks are easily removable.
Add an extend-a-stay fitting.

the curtains I currently have up are pretty heavy duty, but are a woven-type material with little holes where cool air could seep in, so I was planning on finding a material that is thick and not so porous.
The best material I've found is called Insulbright. It is a sandwich of cloth, Mylar, batting, and then you add your own interior cloth after that.

As for my holding tanks, they are not directly exposed to the air underneath, but are located in the storage compartments, accessable on the sides of the RV and all compartments are carpeted. Do you think this will keep them insulated enough to avoid freezing? I'm not sure if there is any insulation in the walls of the compartments or not. What if I found some cheap insulation that I could just shove in the compartments and surround the tanks, would that be sufficient? All my tanks are in these compartments, so do you think skirting my RV is crucial?
Insulating the tanks will not keep them from freezing in extended cold periods. There MUST be a heat source to keep them unfrozen. Are the drain valves inside the compartment(s)?
