Hmmmmmm! Very disgusted!
Have you tried the air conditioner on shore power? Check it on shore power and check the amperage. It should hover around 15 amps with fan on high and compressor running.
Dometic states generator size required for these units is 3500 watt. The Onan 4000 is plenty.
Might check the voltage output of the generator. A loadbank doesn't care much about voltage but that Dometic A/C will.
