[tentcamper]

We went camping for the first time with the TM a few weeks back. Each night it dropped into the low 40's. We only brought one 1500 w heater and it did great. It only ran about 20% of the time and keep the camper at a nice 70 degrees.

Base on its performance I would think one heater is good for us until about 30 degrees. When its going to drop below 30, we will bring our second heater and run it on the 800 W setting. We never had an issue running the two heater one on 1500W and the second on 800W, with our previous campers on a 15 amp breaker.

For dry camping we bring our 8K BTU wave heater, I still need to plum in a quick disconnect on the Low pressure line. With this camper and the performance of the 1500 w elec heater. I think the 8K BTU heater should be good to about 30 degrees before the furnace kicks in.
