Yes my Go Power 2000w inverter runs my Dometic 13.5 with ease. For about the same space and weight of my 4x GC2 I DIYed a 1200 Ah LFP battery. Easily holds voltage above 13.0 under extended heavy load.
Although my 4x GC2 would run the A/C for at least a few minutes while testing. Never tested how long they would run the A/C.
did you add an easy start? i have the gopower 2000watt inverter in my 5th and have never been able to run it.
I would imagin the age of the batteries could be playign a part also if that is so, to many unknowens and the OP isn't coming back to answer it seams.
