Espar heater would be great, but how to deal with the diesel hookups. This is a truck camper. I do have a diesel truck, and am thinking of an espar for heating the engine in the morning. But seems like a pain running lines and quick couplers to the truck camper.
Clearances on the dickinson heaters are not a problem. I looked at those as they are made for small spaces. And I like they way they exhaust. The propane heater is a little spendy. Hoping to find a used one. The solid fuel heater is on sale now for $349 which is almost low enough to convince the finance department (wife) we need one.
