Lately we have noticed the cabinet doors under the main TV area are misaligned, suggesting the outside wall is lower than in the middle over the frame rails. Using a level, I can see floor slopes to the outside in this area and under the shower, which is about midway between frt. and rear drive axles on this 45 ft. coach. So today, while pulling out of a driveway onto a crowned road, I again experienced a cracked driver's side windshield. TS did install the X-bracing before they closed up, so I thought I was somewhat protected from this occurrence.
Now I'm wondering if I have broken frame members in the basement area which has led to the door misalignment and enough flexure to crack the windshield.

Has anyone experienced any of these issues and where might I find a good frame shop to have this checked out? Also need a windshield replacement vendor. I'm now in the Minneapolis area, heading south from here to Dallas.
