Currently the sensor in the grill on the main unit is the stat, but yes it is near the entry to the bedroom. There is no wall control other than the remote that has a little bracket to mount it. I'm not against freezing the bedroom as we like it cold, but my thought was to mount one thermostat on the wall that is near both areas. If that isn't enough, then I could run a sensor into the bedroom for that unit.
It would really be simplest to just repair the circuit board on the failed unit, but if I can't find one, I have to replace the ceiling assembly and thermostat requiring running wires for a new thermostat. If I'm running wires (which will be a huge pain) then I might as well do it the way I want it the first time.
What I would like to solve is to be able to run both units on 30A by alternating between them. I know some old campers were setup this way, but I figured there is a better way to manage it now. I've seen some thermostats with several zones, but I haven't seen anything that shows exactly how these need set up and what would be required.
