How hard would it be to switch from Dometic 3316250.012 to a Dometic 3314082000? I have a 2018 Heartland Big Country and the absolute hate the most is the thermostats in this thing. I have 2 A/C and they have their own thermostats. One in the master and the other for the living room and big furnace. The thermostats that are installed have three wires going in it, while the other has a plug in that looks like a phone plug in.
