It all depends on just how cold it gets. My first two TTs did not have enclosed underbellys. They were good into the teens.
This last one with a heated enclosed underbelly with factory insulation gave up at about 6 degrees.
Of course every TT is different but, I do not believe that putting room temp. air down there will do much more that make the TT colder inside.
BTUs are BTUs, and a electric heater doesn't have nearly as much as the TT furnace... And BTUs are the most important factor.
My point was there are what I believe over concern over using electric heat with it's lack of heating the underbelly and that concern for the most part is misplaced. As long as you are using say a max of 2 1500W heaters to heat your trailer just the radiate heat might be all that is needed to keep the underbelly area above freezing. If you can't keep the inside of the trailer at 70 deg with electric heat then that is probably still above the crossover point where temps in the underbelly will become a real concern.
As I mentioned it is extremely easy to stick a temp probe down say the hole in the floor for like the water pump and actually measure what is going on instead of simply guessing and speculating w/o any factsa which is IMO what about 99% of these posts about only using electric heat and underbelly temp concerns.
