2014 Fleetwood Storm & Generator shutdown

You can expect the gen of that size to shut down when temps climb in the 100+ degree and it's running hard to run the AC non-stop. It's an overheat protection feature. Safe for the engine, not too comfy for passengers. Smaller entry level MH's (like mine) are poorly insulated and the AC simply can't keep up. Add to that the gen powering the AC, the heat from the road and gen in a compartment and it's simply too hot. I helped mine by insulating heat from the engine bay and adding a vented bay door. Thor paid for it BTW and I had my dealer do the work. Haven't had the issue since but I also have been avoiding driving in the hottest part of the day. Even if the gen kept running, the AC won't keep up anyway in 100+ temps and while I think it's good to exercise the gen, I sort of cringe when it runs that hard, full load, non stop for hours on end (including the AC). I think Onan does too, hence the feature. Drive when it's cooler and it won't happen.
