Thanks for the response Gordon.
The trailer is only a year and a half old, so I would guess that the start capacitor isn't old yet.
The AC was running on shore power for a little while before I attempted the generators so that could have been the initial issue. I attempted troubleshooting the generators for a couple of hours, taking a break to do an oil change and make sure the air filter was clean, cleaned the filter on the air return for the AC unit. So I would guess the AC had cooled significantly by the time I attempted to start it up again.
Three Yamaha's?! That's crazy talk! I'm guessing these people have a couple of AC units on their trailer and need the extra juice.
