WOW! I have a 2005 FS30 that we purchased brand new. It's suppose to have a full walk on roof! after seeing these photo's I am a little concerned about being up there. We have had no problems with the roof yet! I wonder which location that this unit was built at? Does it shown it on the Trailer ID> It's no wonder WW (Weekend Warrior) went out of business - sad to think you spent lots of money for this trailer - only to have this happen - It's only 2 years old.
Hope things work out and you are able to repair it correctly without spending thousands on it...
Cheers
