Winnebago Adventurer Roof issues

Maintenance is one thing, have brake linings checked, get the oil changes, inspect your tires, check the belts. Climbing a ladder and recaulking a roof seam that probably should not need to be recaulked ever is a world of difference. My opinion is that if your roof needs to be checked that often and potentially needs that kind of maintenance you have a poor design. Some have said that they fixed theirs with Eternabond Tape, if it is that easy, then Winnebago should just put the freaking tape on the seam!
