This problem is more common than I first realized a few years ago. Take an air cooled gen, road surface temps near 100, contained in a bin with little airflow, running full bore to power 2 AC's and it simply overheats. On my first ACE it was even worse, the gen compartment was directly behind the engine taking on all that heat. MH manufacturers do not put a lot of gensets in bins with enough ventilation and far enough away from the chassis exhaust. I cured the problem on my old ACE by installing a vented bin door. Thor paid for it and I haven't had the issue since. In ideal conditions it's true they should run without issue, but when they can't get the airflow to cool down, they shut down.
