On our trip we experienced trouble with the main blowing in our MH. On the 04 Advent. they installed piggy back breakers for the #1 AC and the 30 amp main. The box is a 50 amp cuttler hammer. The two together was creating enought heat to blow the main. Out west where it was 100 plus, this wasn't appealing. I went to Home Depot and found a new 30 amp and installed it by itself which worked. There are plenty of extra slots to install it. This left the AC on its own breaker.
