Adding 2nd AC to Class C

jdc1, I was thinking the same thing. We don't need it all the time...but are planning trips out west where it's HOT...and our 34 foot C will be HOT with that front-mounted AC unit....but installing a rear-section unit (as mentioned, in bedroom), and pluggin it in when needed, simplifies matters a ton.

Hi Robert-

I have not done this mod, but there were a couple of long threads over on irv2 concerning it. I can't seem to find them now, but IIRC, both guys ended up using a second, dedicated cord for the 2nd AC as suggested earlier. I too would have to go with external ceiling wiring but the metal raceway channel with a snap cover (sold by HD and others) could be screwed to the ceiling and would not look all that obtrusive, IMHO. Both the installs posted on irv2 used "local control" AC's ; i.e. no wall t'stat to complicate things and of course the AC's fit in the 14X14 hole just fine.

You would almost certainly need to use a 50A pedestal; as I understand it, even if a 30A site has a 20A outlet, you are limited to 30A total. I also read a post or two where it was stated that new campground regulations allow only one cord to be connected from an RV to the pedestal, period ….. not good news, for sure. If that's true, one would have to turn their Class C into a 50A coach, basically, in order to add the needed 20A which could be done, but a lot of work and expense.

Here is a link (Google) with a well-documented install where the guy plans to use a 2nd cord for the add'l AC. The most interesting thing I found was the nifty waterproof wall connector to bring the extra/new power into the coach.https://www.google.com/search?source=hp&ei=V9_nXsy3H5DXtAarlafIAQ&q=add+2nd+ac+to+rv&oq=add+2nd+ac+to+&gs_lcp=CgZwc3ktYWIQARgAMgIIADICCAAyBggAEBYQHjIGCAAQFhAeMgYIABAWEB46BQgAEIMBOgUIABCxAzoECAAQClDqHVjZTGDhZGgAcAB4AIABV4gB0AeSAQIxNJgBAKABAaoBB2d3cy13aXo&sclient=psy-ab#kpvalbx=_gO_nXvrpHNWwtAbjgbSQAg27
