The furnace did keep it comfortable. It was running constant though so we ended up dropping the top for the night. I use Thermarest sleeping pads to insulate the PH canvas and they work great, but I didn't have enough of them to insulate the whole thing.
I only had two of the water cans 2/3's full, they froze solid. Even the dogs water dish in the side door footwell froze solid. I suppose camping in negative temps is at the limit in a SMB the way they are set up. I imagine I will insulate it a bit more in some of my later projects.
The van started fine, although it definitely did protest with some different sounds.
