I had an issue trying to find fuses on my 2008 Itasca Suncruiser W24 chassis dealing with the HWH leveling system. I called them for help. They offered several suggestions which I tried that didn't work. They actually called back several times trying to help (from workers on a lunch break at the factory). They asked me on which day that the MH was completed. I said that I had no idea, and they said that it then could be anywhere. I think that I laughed?
We drove 1,100 miles with the alarm dinging, unable to find the fuses. The control unit was eventually replaced. At one point I told my wife that it has stopped, and she looked at me and said no, it actually had not stopped. My mind was compensating. . . or worse.
