. . . I've read a few reviews from RV users and they all say it will run their A/C no problem, won't run A/C and microwave together but neither will my 5500 ONAN as the entire coach runs off a single 30 amp breaker, so 30 amps is the key I guess except I have no problem when hooked up . . .
FWIW, a Champion 75531i will run my Dometic 13.5k BTU a/c and OEM 1500 watt RV microwave at the same time--as long as I start the a/c compressor first. Total current with both running was about 25.5 amps. Yes, a little beyond the Champion's 75531i 23.3 amp rated output and not recommended. It was obvious the 75531i was on the verge of going into overload, but nonetheless it does say a lot about the 75531i's continuous and inrush current capability.
