backwoodsman - I now have a general idea on what you did for your couch extension. Pictures would sure help when you get time. We just got back from a short trip to Clear Lake, Iowa. Hope you enjoy your excursion.
cheeze1 - I don't think the Trail Lite's had a leaking problem with the slideouts. Out of over 40 owners that have commented in this forum, I believe 1 or 2 may have mentioned the need to fix or adjust the seal. Ours leaked once when we had the slide out and the unit tilted so that the rain was forced to run off the top of the slide toward the seal - my fault. Some of those problems can be easily fixed by paying attention how I park during a rainstorm.
