I have a 30 ft. Tahoe 5th wheel by Thor industries and my wife and I are living in it full time right now as I have moved to Oregon and a new job. It has a slide out in the livingroom/kitchen. No leaks at all. The extra room is wonderful and is making it a lot easier to live in full time. Don't have to worry about bumping into anyone when walking around and we have two dogs also.
Used to have a 26 ft. TT without a slideout and we would have been killing each other by now with it! Would never consider buying another camper without a slideout!!
Good luck,
Sparky
