Hi all and thank you in advance for your replies. I have a 1984 fleetwood prowler camper that I've been working on since last year. Recently, I've had to treat it for mold, and in the interim found out that some of the plywood floor and joists have rotted. Since I'll be taking apart the floor, I wonder how feasible it would be to build a rocket stove outside of the camper and run insulated duct work under sub-floor.
Ana, Welcome to Permies! I have thought about this myself. I think it would work as long as you keep an eye on the temperatures of the ducting under the floor. Don't want to catch anything on fire! There is another thread that talks about this somewhere and if I remember right we were talking about using cob as a heat sink under the camper.
Hi, I too am looking for an external rocket type stove that I can use to heat the inside of my trailer somehow. I don't like the idea of putting a stove inside the small trailer and have been looking for ways to have the heat captured in the trailer but have the actual stove outside. If I find something that looks promosing I'll post it here. If you have any other ideas for heating a trailer let me know.
