There's my 12V vs. 120V choice.
At this point I'm considering this only for extending the time the TT sits 'hot' and usable outside my barn/shop. In other words, "How far into Autumn can I push off winterizing and how early in the spring can I summerize?"
There is no place I currently plan on dragging it to while we are expecting below freezing temps. So, 120VAC heaters will fit my present plans.
However, if I add a high-current line off the tow vehicle's alternator and when parked use a separate converter. 12VDC heaters become interesting
"they do have a heater vent routed to the belly in the official upgrade"
OH! I just got it
They use the cabin heat to keep the space between the floor and the foil warmish.
Gotta think this through more. If heated air is being pushed down there, it has to be able to warm the tanks and then the cooled air has to go [to atmosphere or into the cabin]. Packing the frame with insulation totally ruins that.
