Onan 5500 breaker trips only when driving

Was running the genset on the way to the camp site this past weekend, so had the AC running. The breaker on the generator repeatedly tripped, killing the AC.

Once we arrived at the camp area (boondocked), the genset ran the entire weekend with the AC and never tripped - even when we fired up the microwave.

Seems like the 5500 should be handling the load of the AC just fine.

Fridge is on propane and water heater was not on.

Why would it trip only when going down the road?

Also of interest, we put 3000 miles on it this summer across the southeast and this rarely happened - it did a few times, but not as consistently as it was this past weekend.
