30 AMP RV with the roof air. Look at amp loads. I might not want to overload your 30 AMP with a 2nd unit. I suppose this would work...but not much else will work. Microwave. Hair Dryer. Etc. eat power and you will be blowing fuses or transfer switches.
This summer (Only 1 AC unit) on a hot day after traveling. Stopped for the night. Hooked up to shore power. Powered up the Air, the water heater, and a floor fan...then started the Micro to warm dinner...POOF no power. Transfer box blew up and melted. It was a very hot night...Do do that
