Coleman Digital
I upgraded to the Coleman Digital but was unhappy about the way it controlled the overhead air conditioner and the heater: I was getting a lot of big temperature swings. Well duh, regardless of which thermostat is installed, none will work well if the air in the coach is not constantly circulated. So a small 120v fan circulates the air while on cooling and a 12v (if not using shore power) fan circulates the air while on heating. Miraculously, the thermostat started holding a constant temperature!
