When my coach was new the windshield cracked in the upper right corner. When I went back to the factory with my 1 year punch list of things to be addressed, they installed what's called a Halo Kit in the upper part of the front cap that stabilized the twisting action of the cap. They removed the front cabinets including the TV and installed aluminum braces in a circular fashion. These were welded in place. Then they had a template to resemble the windshield that they used to check the side clearances between where the glass would go and the fiberglass. They had to grind away some material that was too close to the glass and added some in other places. This was 7 years ago and the windshield has never cracked again. There were no steel braces installed in the process and no braces were installed in the generator compartment up to the front cap.
