Heater or furnace?
I would go with a Suburban NT-30SP or NT-34SP, I’ve heard people on this forum say 1000 BTU’s per foot of trailer.
I did a 1975 Tradewind last year and could not find a direct fit replacement furnace, I ended up going with a Suburban NT-24sp. This is how I did it. http://www.airforums.com/forums/f427...4sp-47264.html
I would also recommend buying from Palomino parts: 800-297-5830, there ultra inexpensive, and will ship.
