Thanks for the report. Our 25.2 has over 30K miles, and the windshield has held up after the first one was replaced under warranty. Since then I leave plenty of room between us and any vehicle I follow, especially trucks. And even more behind gravel trucks and flatbed trailers.
Rattles are the bane of motor home folks. You locate and fix one and another shows up. They can come and go. Try turning up the radio!
