If you have good power available, the electric heaters work pretty good. With propane heat, in a trailer with portable tanks, OK but a Motor home has to be moved to refill the tank. Could be a problem. If power is questionable, or voltage drops under load, the heater output drops fast. If you can run two heaters without voltage drop at your power post, you should be OK. Consider an extra, high capacity drop cord for the heater instead of you interior wiring and breakers. If you have space, I like the oil heaters, but for space, we use the small ceramic.
