That's the way I would go. I had a Voltage Toy Hauler and the 2 factory a/c's would not run at the same time on 30 amps probably because one was 15,000 and the other was 13,500. Keep in mind you probably won't be able to run your HWH and Microwave along with them. I can't run them while my Factory 15,000 is running, it will pop the breaker.
