This something else you might want to consider. Got this idea from my brother who lives in his motor home full-time. Bought one of those portable propane gas heaters off Amazon.com, went to Home Depot and bought all the fittings and hoses that he needed to hock up to a outside 30 lb portable propane bottle. His works os good I installed the same setup in my coach, and at night the main heater hardly comes on at all. Now here comes the problem that some people are going to have. Running an open flame propane heater inside a closed enclosure. It hasn't killed up yet. And besided, back in the old days people just had open flame natural gas heaters period and there still living today. my inlaws are an example, the there still living in there mid 90's.
Anyway, something else to consided.
