He said AC, microwave and some outlets work. So assuming he’s running those off the inverter, it sure ain’t the problem if it will chill the camper and cook a hot pocket.
But I’m skeptical if the OP knows what the inverter does and when it does it. He’s probably plugged into shore power when running TWO ACs successfully.
But hey maybe it’s fixed since he/she hasn’t followed up. It’s this weird phenomena of thinking one can post some general gibberish with a question attached and those that would respond are like instant AI gratification and spit out the right answer while being clairvoyant to the things that weren’t mentioned or aren’t understood.
It’s rampant with kids. Like mine. But also infecting old and middle aged people quickly. lol
