Hey Scott! The Waltech Vision 2.0 # WA74FR can replace those thermostats if they are Dometic 3-wire single zone, 12-button zone CCC, or 5-button multi-zone. See the attached photo. I'm assuming these are R410A AC units (pre-2025). If they're newer R32 units the thermostat is not compatible. The same is true if it is a Dometic 4-button thermostat.
What trips do you have planned with your Open Range this season?
