There was a leaked '02 internal Coleman memo that admitted to a 10% failure rate on ABS roofs.
Just for the record there was no "leaked" memo vis-a-vis the infamous Fleetwood ABS roof failures as several years before
2002 the company had hosted on their website an open letter addressing these issues as they saw them at the time, circa 1998. The failure rate publicly acknowledged at that time was 15%, 'though many of us who suffered this debacle personally because we owned an ABS roof, firmly believe this failure rate was much higher, easily 50% or more. There are currently three ABS roof Fleetwoods on my own street, one is fine the other two are totally shot, and as well the ABS roof on my own 2000 Santa Fe suddenly de-laminated along the sidewalls near the front lift arms for no apparent reason three years into ownership.
IMO, as far as Fleetwood's ABS Strata roof that was produced from 1996 to 2003 inclusive is concerned the issue of whether you get a good one or not is strictly
a matter of luck ... i.e. you either get lucky
or you don't.
