My 5.5 KW Genny works perfectly. Is your gas tank near full? They could shut off not far below a half tank indicated and start dying after a couple of minutes. Another issue with Onans dying is having the oil level near the full mark. Keep it below halfway full on the dipstick when screwed all the way in.I bought a 2022 Entegra Vision 27A 6 weeks ago. It was a nightmare. The generator would only run for about 2 minutes, in Texas during this heat you have to run it while you are driving to stay cool. Both cab windows were loud; the drivers side was just SCREAMING! We wore ear plugs and yelled at each other. All of the cabinets flew open as you were driving. The kitchen drain leaked dirty dish water down into both cabinets below it. A 3/4" piece of paint just flaked off. I made a list of 11 things and took it back to the dealer. The dealer has had it for 11 days so far and they haven't even looked at it. It was NOT FUN driving a Screaming Hot box down the freeway. You can guess how my wife feels about it. I am already looking into the lemon laws.
I had a very loud passenger window that wouldn't lock correctly, but I was able to fix it and now it is quiet--at least until I open it again. It would rattle of the slightest bumps. I will jave no reason to open it again, so I will just leave it closed as is.
Problems I had on my first long trip was two levelling pads fell off and the awning blew apart in a high wind gust while in Florida.
And a few small issues, such as a rear tire that I could not fill up with air, was fixed by the dealer before that trip.
