Example complaints
Brakes: “Failure of workhorse custom chassis hydro max (redundant brake system) due to blown brake light fuse. The power assist for the braking system is run off the power steering pump and should you lose the serpentine belt or the engine shuts down there is a redundant electric motor to provide power assist tot the brakes. But, should you lose both you have no brakes per si on a 26,000 motor home.”

Upon arriving at our camping space, we noticed the top of the windshields were bulging out from the roof. We covered the roof and top of the windshields with a tarp to prevent rain from coming into the bus. We contacted Newmar's customer support via email and telephone to determine what could be done to repair the windshields. We contacted pace glass in texarkana, tx to make the repairs using schematics provided to us by Newmar. …”
