lots of anti HWH sentiment here
I want to offer a contrary data point...
We've owned our coach a few years now. During that time we have dealt with several RV repair folks. We've had multiple bad experiences, but our visit to HWH was one of the best examples we have had of outstanding service. The only thing I'd rank equal was using Cummins Care in Spokane.
Having been there, I'd cut them a little slack. It's not a huge office running everything. Those folks are busy and work hard.
As some background for why we visited them, we had our left rear jack "repaired" in Spokane, but it still leaked. The Spokane shop didn't want to wait for HWH, so their local 'hydraulics guy' did a repair. That whole fiasco was one of those bad experiences.
Fast forward several months to our visit to HWH. The tech there told me, "most shops can't rebuild our jacks". They didn't even try to repair it, they simply replaced it with an in stock item. We pulled in the evening before appointment and left the next day.
I realize not everyone can go there directly, but if you can, I recommend it.
