What temperature do you keep thermostat on while camping.

I use a ceramic heater and turn on the A/C fan. I position the heater under the return so the heat can flow through out the trailer. The trailer stays right around 70 deg. This works on all but the coldest of nights, and when it gets that cold I turn on the furnace to supplement the ceramic heater. Otherwise you can blow right through a 30 lb tank on a long cool/cold weekend!

The A/C gets set at 68. This way when it gets in the middle of the day the trailer is cool enough to still be comfortable.
