James,
I found this site in my search for a way to heat that travel trailer (that I don’t yet own). The guy with built his heating system for his RV out of a car’s heater core and attached it to PV panels for power of the pump motor and fan, the heating of the tank is [accomplished with] a propane [burner]. This might be something of interest to your readers as it’s something I’m going to need since the travel trailer I’m looking in to getting is older and needs a new heater. I figure why buy new or reinvent the wheel, I’ll find an efficient way to power and heat this travel trailer with minimum funds, someone has already done this somewhere and it’s out there on the Internet Thanks, – Fitzy in Pennsylvania
