We have a 2004 Jayco Designer 29RLTS with 3 slides. There are no leaks anywhere, and no evidence of any past leaks. Right now it is sitting outside beside the garage, with all 3 slides open, and we have had over 4 inches of rain in the last 48 hours. Still no leaks. All 3 slides still work just fine - no problems. We take the trailer out to a CG about once a month, and are very happy with the quality built in by Jayco.
