I have a 2022 3500 170" Ext with a factory rear AC. I had planned to have the Rear AC Drained so we could replace it with a 12v Unit, but when we brought it in to have the rear system discharged, we were told that unlike previous model years, the front and rear systems were not separate and the only want to drain the rear was to drain the front AC. I'm not sure if I am dealing with an inept tech, or if there truly has been a change for the MY22 or what. For obvious reason, I do not want to risk losing the front AC.
Any insight would be appreciated.
