Mike, we plan on doing more 'Off grid' camping. The Propane furnace we all have on our trailers pulls quite a bit of 12 volt power when the fan runs, it would almost deplete the stock 12 volt battery in one afternoon and all night of running, then there is the Propane usage, the stock furnace is only around 40% efficient, you lose 60% in the exhaust, so that depletes your on-board Propane. For extended stays without replenishment, the small heaters work super.
They are around 99% efficient, and use little or no electricity, depending on the model. The 20,000 BTU with fan model uses less than 1/2 amp of electricity.
We don't plan on being in severe cold weather, heating the underbelly is not an issue, so the small Propane heaters will keep the interior comfortable.
Good questions.

Thanks for explanation, Ozz. That makes sense. Now you got me looking at one. Thought the OEM heaster was more efficient than that. They do make a good hand warmer when you are outside. LOL
