We traveled to the HWH factory in Moscow, Iowa in July of 2014. They removed the hydraulic leveling system in our coach and replaced it with an air leveling system. I had issues with leaking jacks and they were obsolete. Stayed one night with electric outside of shop. The next day pulled onto a lift two stories up, hooked up to 50 amp, ran a/c, had tv signal...stayed in coach for three nights. We watched the night shift work in shop, had access to showers in plant. During the day did some sightseeing. Worked out great!
