My 30'5r only has 1 ac and 30 amp service and I'm determined my next rig will have 2 Ac's and 50 amp service, if for any other reason if one AC fails your trip wont be ruined. It gets awful hot and humid here in Texas and Its hard to keep our rig comfortable when outside temps are above 95.
I intended on adding another unit to mine, but it turns out the roof antenna is right behind the vent so it would have to be relocated and I would need to run a seperate plug to go to the pedestal since I only have a 30 amp service.
