I guess I left out a few details. I meant an onboard generator in a toy hauler. An Onan 5500. We will be heading to our destination in 90-degree temps. The trip will be about an hour and a half


Wait, toy hauler FW or toy hauler MH? The answer would be different. If this is a FW I wouldn't as no one is in the RV to know if there is an issue with it. A MH I would certainly run it while travelling.

Toy hauler fifth wheel. I didn’t run it, but am finding it is taking forever the the two 15000 btu AC’s to catch up. My infrared heat gun show it almost all areas of the camper over 100° when we parked. Two hours later high 90s. I finally open the turbo cool in both bedroom and in the garage which eliminated the duct system. Hoping to cool those down first and pull the heat out and will then work on the main living compartment as it gets cooler tonight

It's specifically states in the onan microqiet manual that they tested these generators to 120°F ambient using travel trailers that the company owns.

I have experienced overheating shutdowns that were actually caused by the fuel pump. A brand new Onan brand fuel pump solve that issue.
