I would do it in a second. My trailer is not wired for a second A/C, but during the summer running the A/C water heater and fridge on electric, microwave, coffee pot, we frequently trip breakers. I just built a break-out box to use the 50A service to run two 30A legs. Not as good as 50A, but it will give me 60A of usable power, plus, I have already installed an additional 20S leg to run space heaters.

I now have a Keystone Outback, but I try to help when I can.
