Since I would only need the heat late in the year, like October and November, why not make a heater that was external like the doghouse. The heaters in most travel trailers are ducted, I could build a box that sat outside and housed the furnace and run the duct up into the floor. That way if I wanted heat for the trip, I could throw the heater inside and take it with me. That way it won't be taking up valuable real-estate inside the tear when I don't need it. I could probably pick up a used furnace at the salvage yard for less than 50 dollars.
I could do the same with an air conditioner, which is only needed here in Michigan for a couple of months of the year. Plus if we are going wilderness camping, I wouldn't need to bring the air conditioner as there is no power.
Any thoughts?
so where has this taken you ?

have any of the answers helped you or what did you do?

got any shots??
You site has helped me come up with some inventive thing
I like the candle idea myself but my only question is about the exhaust and the excess wax and is there build up in the exhaust pipe.
I was given the body to a apple G5 and have been gutting it. The body makes a nice table and it has 5 fans and 2 huge heat sinks
As you see below I am building my trailer as we speak.

what you see is half of my trolley top. so there is a mirrored one on the other side.
The back window will get a small circular air vent in it. one on each side. One air in one air out.

on the inside of each will be placed one of these

a galvanized flange. then I can attach either electrical conduit or galvanized pipe fitting on it. they will bend down to the cookie tin.

with the one that is air in being below on one side and the out being at flame level, allowing heat to build before it exhausts out the out air side.
above the tin will be this will be the big big G5 heat sink the photo is to big to show
http://erecycleronline.com/media/catalo ... 0337_5.jpgit has something like 15 open to air vents and copper the goes up through them and is connected to a copper or brass heat catcher. This catcher will be attached to the top of the cookie tin.
I have a van that is a double unit.
http://www.powerbookmedic.com/xcart1/im ... image.jpeg that I will use as the vent fan from the outside and heater fan with the vent closed or open.
The fan will be mounted so I can rotate it up or down or make the air go toward us or out the vent. The Vent will be at the back of the trolley facing backward and horizontal to the top.
I hope you did not find that to confusing but I tried.
