Slide Topper Rec?

I agree with ScottG above. When we ordered or present trailer, I insisted on an Alumaguard slide topper as part of the deal. I'm glad I did. It really is a cut above the junk we had on our previous rig..

I suppose those of us who have never had them continue to live without them and we're getting along just fine. Those who do have them seem to really like them. And then there are those who have problems with them, billowing in the wind, getting dirt under them are the two biggest offenses.

I suppose, someday, I'll get to the point where I won't be able to climb a ladder any more to brush off the slide out tops. When that day comes, I may be a little more open minded to getting the slide toppers.

For the most part, I think they do help to keep things like leaves and stuff off. But there is still the problem of stuff blowing under them too. And then if you retract the slides, there's the risk that any hard debrie, like small sticks or whatever, could punch out and damage the slide seals. For me, it's not worth the risk (yet) ... but maybe someday my ideas will change.

Can't recommend a particular brand, but I'll say that I wouldn't be without them.

If you don't mind spending more, the Alumaguard is sure nice.
Otherwise, I installed the cheapest Carefree many years ago and it worked great right up till I traded the last TT in.
Some will disparage toppers but they work great for us. Keeps tree junk off s/o roof and keeps the heat down on the roof of the s/o - which is considerable.
One tip I have is to try and give it an extra turn when installing. I did so and never had a billowing or puddling issue with mine.
Also, try to mount it with the most slope possible. Water sheds off it better.
