We run our AC plugged into our garage, as we don't have AC in the house. This summer we really have enjoyed it. That being said on the day's that we were in the high 90's, we did pop the breaker once, when I was vacumming the trailer with the AC running. The chest freezer and our extra fridge are on the same circuit in the garage...or actually they were. We just re-wired the outside box to its own breaker, so right now the trailer has its own dedicated "plug", while in the driveway. When we move the trailer to the other side of the house...we are still deciding if we are going to give it its own dedicated circuit and if that is going to come from our garage or house.
The joys of having a garage that was a metal machine shop for 30 years, we have 3-phase 220 into our garage and lots of capacity to do a dedicated drop.
