Has anyone brought their Rockwood fifth wheel back to the factory for service? Our new 8289WS has water leaking through the wall structure of the wardrobe slide (not around the seals). We don't think our dealer's service department is up to the job of fixing it. Trying to reach the factory warranty department now, but they aren't being very responsive. Would like to bring our trailer directly to IN to get it fixed right. Wondering if anyone else has done that.
