2017 Canyon Star and flapping topper

[Leland0311]

The leading edge of the driver side slide topper has flapped in 10-15 knot wind since it was new. The topper will be replaced under warranty next month as there is now a 2'' rip at the front edge.

For some reason, passenger side topper doesn't flap even though it get's the wind directly on it.

First toppers for me. Had a 5ver with 4 slides, for 8 years, all without toppers, and never had a problem.

I know there are lots of ways to stop the flapping. My Newmar tech told me the flapping topper was installed incorrectly.

Question is this. I camp a lot in SoCal in the Winter and would have serious concern if a storm came up, esp. at night. Putting in the slides would be a royal PIA.

How much wind would prompt someone to put their slides in?

The offending topper has flapped at 10-15 knot wind. What'll happen at 30 knots?

If a topper ever gets damaged from wind, I'll be removing it permanently.

Just wondering how common this problem is. For some reason, I'm thinking this shouldn't be happening to a new topper.

I did not have this problem on mine, many days here in CA with to much wind to put out awning.

What brand topper do you have? Mine is Carefree and does the same thing. Newmar considered it stretched and wanted to replace it for around $550. Instead, I decided to loop a nylon strap around the slide to mitigate the flapping. It works for me right now in windy conditions. I personally think it is a Carefree design and manufacturing problem.
