A/C circuit trips while running off generator while driving.

Just got back from a 2000 mile trip to Oklahoma and back. The outside temps were in the 104 to 106 range. Two time while driving with the generator running and the front A/c on the A/C circuit breaker tripped. This happened just a few minuets after turning the A/C on. When stopped for lunch and running the A/C off generator it does not trip, only while driving. The roads were pretty bumpy so could the bumps be causing the circuit breaker to trip. Could it be a weak circuit breaker? It works fine off shore power and if I am stopped while running of the generator. Thoughts

They can trip from the bumpy roads. You are talking about the CB on the genny?

No, the C/b for the A/c. The gen c/b dosen't trip.
