We approached the problem differently - when we added a second A/C unit (Monty was prewired for the second A/C) we told the dealer we did not want to power the front A/C off of the main 120v electrical system. They removed the leads from the posts on the back of the Distribution panel and connected them to the leads of a heavy duty 2o Amp extension cord via a junction box (to ensure they didn't stress the connections). We then routed the 20 AMp cord through the basement over to the convenience center. In effect the 20 Amp cord is hard wired to the front A/C and nothing else.

As noted in other posts, most campground pedastals have a seperate breaker for the 15 amp plugs. At the north east rally, even though we only had 30 AMp available for the coach we were able to run both A/Cs at will. This also has the advantage of anyone walking by only seeing ONE black power cord running to the pedastal. Most folks don't realize the extension cord is powering an Airconditioner and assume it is awning lights or some such thing. (Basement entertainment system, etc.)

Even if your front A/C is already connected to the main bus it should be very easy to retrofit this "solution" to your rig.
Im doing the same thing when we install our 2nd air conditioner. Mainly because it will allow us to stay at some more rustic 20amp sites and still have a cool bedroom.
