I had new windshields installed by RV Glass Solutions in Elkhart, Indiana in December of 2023. They inspected the seal and did not replace.
In December of 2024 I went to pick up my unit from storage and noticed that both pieces were cracked in the lower outside corners. It was parked on a level concrete pad and did not have the levelers down. I contacted RV Glass to inquire about the warranty and was informed that these were "stress" cracks and were not covered under the 18mo warranty.

I wasn't terribly surprised that it wasn't covered under warranty. Frustrating but what can you do.
I drove the unit and within 5 miles the cracks had expanded considerably.
I then parked it again to have some service done. The service shop called a few days later and said the windshield had basically completely failed.
My insurance agent recommended that I not make another claim (I've had 4 in 3 years for various other vehicles that have received hail damage.) But, how do I get the windshield replaced and have confidence that I'm not going to have this problem again? I can't afford a new windshield every year!
