Slide Topper Air Dam

[EasyDoesIt]

Those who have Toppers on their slides know the frustrations of winds affecting the toppers billowing them up. Even with the slide in, the topper can and will billow out. I had removed the topper on my full wall slide when I encountered 30+ side winds while driving which billowed out the topper. I could NOT keep it in. Drove 30mph until i could get to a town to get help to remove it. The pressure on the side of the coach blows under the topper whether it is pulled in or not. I have installed an air dam under the awning roller to keep the air from blowing under the topper. I found a z shaped Hot dipped and primed flashing (Deck Header Flashing) 8 ' Long at Home Depot in the flashing department. It has legs of about 3" X 2" by 1/2". I bent a 1/2" Relief of about 1/8" down on the 3" leg to make sure it would not snag the topper fabric. Since I had the topper removed I had access to crimp the 1/2" leg over the top of the slide. I painted the side that shows black prior to installation. I had to pull it down to relieve the pressure on the roller to assure operation of the roller as the slide is retracted. I have not done the other slides yet but will probably do them too.

On A&E's they have an optional anti-billow device that can be installed. I have them on both my slides covers. They must work as I've never had any trouble with them unfurling.


I've been searching for a link to it but haven't found one so far other than a small picture of in on the Camping World site.

On page 8 (HERE) they show how to install it.

According to that I installed mine wrong! They say 12:00 o'clock and mine are at 1:00.

My "lock" broke off in the side wind I experienced. That will supposedly prevent billowing only when closed.
