Fleetwood introduced it's ABS Strata roof with the 1996 model year and first generations were manufactured in house by FFT until they realized there were just too many warranty claims. They then farmed it out to a 3rd party manufacturer who supposedly could overcome the various issues with this roof, never did, and eventually were forced into bankruptcy because excessive warranty claims continued. FFT then resumed manufacturing the roof themselves until it was discontinued entirely for the 2003.5 model year. Who's to know what changes in the manufacturing process may have been made by either company during those 8 production years to overcome the various issues with this roof? The seamless ABS roof was certainly great in concept but a disaster actually manufacturing it.
