Generator Run Time

Also, bear in mind that the 5500 onans draw cooling air from below. Its possible dirt or debris could be hampering its cooling. Ive ran mine 24 hrs a day in the Texas heat with both a/cs going. Never a problem.

Just a thought, maybe run a mid sized electric fan on or into the gen set compartment. They draw, at max, about an amp so shouldn't really add to the load significantly. I did that with the smaller gen set that I had in the bed of the truck. It was running at near max capacity and with the fan, the air temp stayed much cooler in the bed area.
