You probably have a 2-piece windshield. Those of us with 1-piece ones are more susceptible to the issue, plus glass cracking, when parked on uneven ground or experiencing bag air loss and/or not properly leveling. But body twist can affect 2-piece windshields also. Ours had the extra problem of being mis-mounted at the factory.
Most RV Glass Solutions facilities across the country are quite experienced with these issues and very capable of properly dealing with them. I’d suggest looking one up in your area. They are club sponsors and may offer a discount. Some repairs may be insured, so ask your agent or RV Glass Solutions.
Not just any body shop will be familiar with motorhome windshield seal situations. Many here have had quite a problem getting theirs resolved, but usually single piece ones are worse, especially the earliest attempts at them, ca. 2005-2007.
