My daughter has a 2004 fifth wheel. We had a 15000 commercial domestic AC put in. Was told it will freeze her out. It's connected to ceiling assembly. Blows cold but can't run on anything higher then low or the breaker trips. It's a 30 amp rv. Anything we can do to get it to handle this unit. We turn everything off and still only can run in low.

Something is still running then. Refrigerator, water heater or something else running. Should not be pulling enough to trip. What is tripping. Breaker on pedestal or a breaker on the panel inside. Or something's no not wired right on the unit. Almost no difference in running fan on low or high maybe 1 amp or so.

On a 30A service you must make sure everything else is on gas. Refer and WH on electric will each draw enough to overload.

To be clear, is it the 30 amp breaker at the post tripping? Or the 30 amp main breaker in the trailer tripping? Or the 20 amp A/C breaker in the trailer tripping?I had the 20 amp breaker for my A/C start tripping for no obvious reason. Replaced the breaker with a new 20 amp breaker and no more tripping.

I was thinking that too but 'commercial domestic' sounds more like a home unit.
