One other thing. I have an extension cord going to a 20 amp wall socket that hooks up to my 30 amp cord using an adapter. It has never been a problem.
Are you saying you are running your rig off of a 20Amp circuit? If so, I would say you've been lucky to get it to work at all.
Certainly the higher heat can be a problem. Not knowing how long the extension cord is, but the resistance in the wires increases with temperature. As the wire resistance increases, less voltage gets to the A/C and the unit has to pull more current to try to compensate for the reduced voltage. Also, every connection, including the adapters, adds resistance to the path. And speaking from experience, if your 20A to 30A adapter is one of those "hockey puck" looking things, they're garbage and have a relatively short life span.
When you use your generator, you don't have those losses to contend with.
My guess is that you'll be fine when your rig is connected to a true 30A 120VAC connection, assuming the voltage is proper. That assumption, by the way, is not always a safe one to make. If you don't have a voltmeter, I'd recommend getting one and learning how to use it so you will KNOW if there is a problem with the supplied voltage to your rig.
Good Luck,
