Does anyone know if you could chain the main thermostat to both units? Perhaps buy a different face for the Coleman and run control wires to the thermostat. I’d be happy to set one thermostat at say 75 and let the two work together to make it happen.
The issue with manual control in the bedroom is that it freezes you out at night. If there was a control that allowed you to dial in a temperature on the bedroom that would be another option.
Thor uses two thermostats for their cheaper coaches with two A/Cs. You can refit both AlC to work with a single thermostat but the cost is significant, about $500 for the parts (thermostat and A/C control box assembly). Cheapest solution is buy a 08-033 cool control unit for the bedroom A/C and another wall mounted thermostat since your bedroom A/C is not ducted. The cost is about $100 for the parts and thermostat. The nice thing about a mach 8 is there are three individually controlled motors -compressor, interior fan and condenser fan, so it is quieter and less air flow on low speed interior fan.
