ok, so you can search for how to on leak repairs. you can search for how to find a leak. but this question is on the life cycle of leaks. i have noticed that alot of you have had experience with leaks...
YMMV, solution to leaks is not have them. I am anal about roof, window and slide maintenance. Several times a year I am checking roof seams, window sealing, slide seals and wipers and any other place that looks as it could be a problem. Have ample supply of caulk and tape. Unless damage occurs, this should negate leak issues.
