My friend Brian want's to add a propane furnace to his campervan that's like the one in my rig, but doesn't want to buy used. As far as I'm concerned, the newer types just plain suck when it comes to winter heating with very limited power. He doesn't want catalytic, with the attendant moisture problems & potential oxygen depletion. Besides, AFAIK, they're not legal to use indoors in Canada. He has a Webasto diesel furnace, but it uses too much electricity & costs a fortune to run. He's looking at maybe getting a Dickinson P9000, but they're pricey. So far, I haven't been able to source a new convective RV furnace & am hoping someone here might know who still makes them. I know that Amazon sells home units, but not RV ones. Anyone? ..Willy.
