Our 5er is set up for a 2nd AC unit up front including a 50 amp service and dedicated 20 circuit with 12 ga wire in the ceiling near the front ceiling vent. I'm thinking about installing the 2nd unit ...
Camping in Moab, and it's blazing hot. Sure wish we had that second AC right now. We've gotten by with one closer to home, but just one won't be enough if we keep taking vacations like this one.
Also would be nice to have a second as a backup. Our original AC conked out on our very first trip with this camper. A second would at least have made the nights bearable.
