When my passenger side started popping out, a company in Chehalis fixed it, and when they pulled it out the rest of the way, the mating surface was dirty, and it appeared WRV never cleaned out the place the window and urethane glue/sealant was going to fill. When A-1 Coach Glass fixed the drivers side later because of a rock chip, they found the same thing on that one too! Both places required us to level the coach with the SLIDES IN. A-1 Coach Glass wants the MH to sit for 24 hours before you drive it or un-level it because that sealant needs to set up. I liked them better than the glass place in Chehalis, WA.
