IF the Motorhome came with 2 AC units the OEM always installed a large enough Genset to run BOTH AC units. A 5K and larger will run 2 Roof AC units. Doug
I bow to your greater experience......but I'm not sure it "always" applies.
I'm pretty sure I've seen some units with 50 amp service and a generator that will only run one. Maybe that was a class C or 5th wheel.
Anyway, 7500 should be plenty.
If it was made that way initially, I don't understand why it would work differently on shore power though......unless maybe the first one starts and drags the voltage down to where the second one won't start.
Probably not a "easy" fix and likely will require professional service.,
