I believe it's likely you can retrofit a LP furnace. They are essentially a box with knockouts and available in many different sizes.
There are also mini wood furnaces that you can vent to the outside.
Really, there are a lot of options.
I am going to look into that again. We don't have a permanent LP on board (just the little canisters), and weight is an issue (hence the bare bones camping) as we are driving a Tundra. I literally made a spreadsheet with weights of all the items we bring. Dang Tundras with their lame max payload. I think ours is 1500#.
