Unfortunately, the Dometic thermostat that Escape uses to combine the AC & furnace in one unit requires a module that is located in the AC. The current thermostat has 3 wires - a ground, +12V, and a "sense" wire running to the module in the AC. While it may be possible to move the module to a new location & use it to control only the furnace, I don't know if that is possible.
If not, you would need to rewire the run between the thermostat location & the furnace to provide 2 wires & change to a furnace only thermostat. Most home type thermostats use 24V AC from the furnace to operate - won't work with the trailer system. There are a few digital thermostats that have an internal battery, or you could use the Dometic manual "clunk" version.
