Out here in Quartzsite AZ and had to fire up the furnace for the 1st time. I want to install an extend-a-stay type connection so I can use a larger tank but DON'T want to use the furnaces due to them ...
We used a Olympian propane heater for the last 25 years in our pop-up. Dead silent and no electricity needed. Needs ventilation because of oxygen usage and humidity control. Pop-ups already have lot of ventilation.
Haven't tried in our new class C yet. Sure you would need to let some of the moisture escape.
Wonder how much more efficient the ventless propane heater would be since you would have to have some windows open. 12 VDC conservation would be king with these heaters.
