2014 Fleetwood Storm & Generator shutdown

Hi guys going thru the same issues.A Cummins shop replaced fuel pump after setting and running at shops lot all day! drove 15 min and it s/d yes it was hot 104 and in the south west you don't have choice! went to the dealer, they took it to an rv power service center, found that it had excessive heat rise causing s/d dealer is going to contact Fleetwood there is suppose to be box/baffle kit. this is a improper install, I call it a design flaw!

What make/model is the generator?

Thank you all for the great info!. You guys gave me a pretty good idea what to look for... or what to tell the dealer/Fleetwood when I reach out to them ... Thanks!!

BTW, you should have no problems dry camping. It's really an engine heat problem so if you aren't running the engine, the generator should work fine.

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.

I have a 2011 Fleetwood Storm 32 BH and had the exact same problems. The problem sounds to me like vapor lock. Fleetwood did three things to try and fix the problem.

1) They moved the generator exhaust back behind the engine towards the rear tires to try and move the heat away from the engine.
2) They Installed a heat shield between the main engine and the generator to try and minimize the heat buildup under the generator., and
3) They installed a loop in the gas line supply to try and prevent the fuel from vaporizing before getting to the engine.

These actions all helped, but sadly, failed to stop the problem. I mostly notice the problem if I slow down or come to a stop. It also occurs much more frequently when it is hot than on cool days.

I firmly believe that the only thing that will solve this problem is a vented baggage door in front of the generator. Go ahead and contact the dealer, but when your warranty runs out, I'd recommend a vented baggage door. Enclosing the generator in that space makes absolutely no sense at all.

This has been a real sore spot for me but I have purchased a new motorhome and will soon trade in the old Storm.

Are you getting any codes with the flashing light

Maybe you might want to call your dealer and ask them? Continuing to use a genny that is known to have issues may not be a wise course of action.
