My old 91 Foretravel has a Onan 7.5 kw diesel genset It also has a 250lb propane tank. It holds about 48 gallons of liquid propane.I fill it in the spring and Fall. I leave the 2 furnaces on in the winter on a real low setting to keep plumbing warm. it doesn't take much propane to refill But my coach is super insulated also Thats just how they build these things.
