One thing I did in my small C, partly to reduce battery drain, was to relocate the furnace thermostat. I put it where's it's easy to reach from the head of the bed. (This was also done to reduce or eliminate the blasts of furnace noise that awakened me too frequently at night.)
Now I usually go to bed with the furnace off. I can heat the coach up before getting out of bed. If the cold wakes me, I can easily turn it on for a few minutes, then off.
