Hello all, just wondering if anyone might have an idea why our ONAN generator will not run for more than 10 mins. while we are in motion. It runs fine when we are not moving. This is on a 2005 Coachman class C motorhome, with 50 hrs. on the generator. We have never had this happen with our 2 older motorhomes. I will take it to the dealer as soon as I can, but were just wondering if anyone has had this happen to them before. Thanks for any information you might give on this subject.
