Hi Chuck Linn,
When the slides are closed, do the toppers roll up into a metal enclosed cover? I do not know Fleetwood. I do know Newmar. Newmar toppers are enclosed in a metal cover. The Newmar factory does work on other Brands. Consider giving them a call and see if they are willing to take a look at your situation. The trip is a good excuse to visit the Amish area in north eastern Indiana. There is a lot to see and do while they work on your coach. They do fabulous work. The only negative might be the lead tech will arrive at 6 AM each morning to begin work! Newmar service number is 800-731-8300.
