Sorry to hear about your issues.
I, too, have a 2015 Revere 32DS. Bought October 2014 and took delivery in April 2015. We've had a few small issues (leaks in grey water drain pipe joints, screw in ceiling of sliding door to front bedroom not catching a stud and sagging, screws in two stabilizer jacks warped at delivery). We also had one significant issue - the main door was not plum. When it got hit with direct sun, it would swell slightly, making the door near impossible to close (would catch at the top left corner).
Our dealer, a small and local place, has been great at providing repairs during and after the warranty.
We get quite a bit of use out of ours - 32 nights in 2015 and will have 38 nights by Labor Day this season.
I'd say build and quality control is par with the industry, which isn't saying a lot for the industry or Shasta. Definitely sounds like you have a lemon. After reading your posts, I'll take the little issues I've had...
