Main slide leaks. Difficulty getting warranty action

A slide topper is a good idea but make them tell you what model they're installing first.
Carefree makes a super cheapo slide cover that only manufacutrures can buy because it's such a piece of junk. It will do more harm than good because it just collapses with rain, stretches out and then dumps it down the inside corner of the slide.
I got ripped off with two of these!
So find out what model and then go on-line and check it out.
Don't accept it unless it's one of the retail models on thier web site.
