Adding 2nd air, converting from 30 amp to 50 amp

I suppose some have managed to run two AC's on 30A but when ever I've run even one the plug got warm.
Adding a seperate plug for the 20A outlets at parks seems like a good idea on the surface but I've always found them to be loose and worn out at any CG's I've tried to use them.

Your on the right track going to 50A in my opinion. It's the one way to not have to worry about power when running two or more AC's.
My current rig has 50A and I would never go back.
