Must be your RV, we have camp out at 18 degrees. the campground turn off all water due to freeze up.
Inside our camper it was 77. Is your under belly enclosed?
WOW! Some of the Toy Hauler people need to weigh in on this thread. Camping in the So Cal desert can get down into the teens at night. No way it could get up to 77 degrees inside my rig! And yes, the belly is enclosed. I have two furnaces. Front half and back half of the coach. To conserve battery and propane, I often only run the back furnace. I set the thermostat at 58 degrees. It will run often throughout the night, but it will stay at 58 degrees. In the morning, I get to slide open the door heading up front and run up and turn on the front heater, and the coffee pot. I have seen 34 degrees on the digital thermostat when I turned on the heater. The run back into bed for 15 -20 minutes.
Often we bring in 3 of the 4 slides. As stated, less to heat. Cover the windows. Cover the vents. I have never used anything but the standard furnaces. I have plenty of batteries and I buy propane to use it up!
Good luck.
