Bob,
I have an 06 3400 that I took delivery on last Nov. Since then all the weather rubber strips that run along the bottom side of the back 3 slides have started coming off.
I have used the double sided white foam tape (approx. 1/16" thick and 3/4" wide) to remount them. Thus far they seem to be holding - certainly better than what was on the trailer originally.
