Dometic AC with Heat Pump Upgrade
Have an older 97 Holiday Rambler Endeavor LE with two dometic low profile ac units with heat pumps. The old units have a little trouble keeping up in hotter temps so I am looking to upgrade them both....

My coach is currently in the repair shop getting a new rear AC unit installed. 13.5 Penguin. Front was replaced last year by the prior owner and they upgraded the thermostat. He told me they had to purchase a control board for the new ac to talk with the other one and the thermostat. New AC is a 13.5 penguin and the shop is telling me I need another control board??
