The joy of a one piece windshield. We have a friend with a different brand who's had the whole front cap removed an rebuilt. Still his windshield has a corner, where the windshield actually poops out. His coach has been to several different glass companies and RV shops, still the problem the persists. I'm hoping the Bay Star is a better built coach than his, because we have one, an travel the back roads whenever we can.
Years ago a Safari salesman told us that 4 point leveling jacks could cause this. That's why Safari used a 3 point jack system, so as to not stress the front cap. There's an awful lot of 4 point systems out there, so it was probably more of a sales pitch than a fact.
Good luck, let us know what happens.
