While the main ac is on and I start the 2d ac the 20 amp breaker on the Onan kicks out a short while later.
Is it possible the circuits are wired backwards on the generator?? OR???? Maybe the ac's should be on sep lines??

I will pretty much guarantee both ACs (although on separate/individual circuits in your panel) are being fed by the same leg by your 50 amp supply....
Which is not a problem on 50 amp park service....
But when running off your generator, both 20 amp circuits (1, 20 amp for each a/c) are being fed by either one of your your two generator circuits.
Solution is to relocate that circuit on your main distribution panel. You want one a/c powered by leg A, and the other a/c powered by leg B.
Ideally, you want main a/c and microwave together on the leg fed by the 30 amp side of your genny.... And the other a/c of the leg which is fed 20 amp side of your genny.
