supposedly, the last couple of years of Roo/Shamrock hybrids, 2009-2010, had a better seal system.
mine is a '07 and i had a retro-fit done on my front bunk, while it was still under warranty.
FR did do some replacements, even for some out of warranty, on the front bunk. some got new seals, some got that and new hinge and some got those and a new door.
even some of the newer seals ones had issues, which i feel were quality control issues from the factory. unless you were getting canvas caught in the seals when closing up the bunk end.
but you should have found water in the hinge area, from sitting or driving it in the rain. this would have alerted you to a leakage problem way before this.
for hybrid owners, the bunk seals/hinge area need to be checked constantly. since you're new to the forum, i suggest you read as much of the expandable section and the Hybrid Forum on RV.net, to educate yourself on the unique issues with hybrids.
