Steve, that is interesting!! Piano, I had no idea they made an infrared LED -- I will check that out. The LED lights inside my trailer do put out some heat -- not much, but it might be enough, especially if the panel is designed to emit infrared.
And Dave, there is a propane furnace, but I don't have a way to vent it to the underside of the trailer. Can you think of a way to bootleg some of that heat to the tanks??
I should add that given the extreme temps, we used the furnace much more than we ever have before -- with a 120 watt solar panel, we now feel like royalty -- "sure, turn on the heater -- so what if the furnace fan is an energy hog?" When we boondock, propane is always abundant -- electricity is usually scarce!
