I was talking to person that bought my 2003 2027, He had a 1998 3023. He said a big concern with the TM's predating the aluminum frame, was the leaking along the roof side edges when the caulk failed. He said in many cases it would leak with none or almost no indication inside. But it would rot the frame along side of the roof frame.

He was looking for a 2003 or newer. He said with the aluminum frame and the new aluminum extruded corner trim between the roof's side and the walls. He said that if you do get a leak from the caulk failing you might never know it and the frame will not rot.

I check the roof caulk every year.

Most the leaks I have read about on the post 2003 models seem to be at the vents and AC unit which seems to be an issue across the entire RV industry.

Other leads that seem very few are alone the roof center seam and a some windows.

I don't think I have ever heard of anyone having water leaking past the bag seals between the two upper shells.
