That was the thought I had. I don't see the electrical system of the camper being strong enough to safely support the heater. I see that you camped in one of these for a while and I looked a little more closely to mine last night and it is also a 1988 sequoia. Do you have and tips and tricks to add about the camper. We had travel trailers when I was growing up and I am in the market for one now. We have camped a few times in the PUP and like it but we would be a lot better with a TT around the high 20' range. I want to make do with the PUP through this and next season unless the deal of a lifetime jumps at me between now and then but I don't have a lot of experience with this one.
