Hey Mike! Since the ceiling controls on the # CM43RR would be too high to reach you can use the Coleman-Mach Signature Mach 15 RV Air Conditioner System # CM32RR with the wall thermostat. This is the ducted version, but the AC itself is the same with the ADB and thermostat being the difference. You can simply leave the louvers open so it dumps air directly into the room.
Since the systems aren't tied together, you could also add an AC like the Furrion Chill Cube # FR59TD. This operates via the remote, which also acts as the thermostat. That would eliminate the need to run wires for a wall thermostat. The Chill Cube provides a lot of cooling power and is also incredibly efficient and quiet.
What kind of trailer do you have?
