Slide Awning taking flight!!!

Recently when traveling down the highway my awning over top of the dinette/sofa will be grabbed by heavy wind and will actually unroll for a second, then retract back in. This only happens in very strong wind conditions but makes a terrible sound and cannot be good for it. This is the only slide awning that will do this, and is really annoying. Does anyone else have this problem? Also is there any way to tighten the spring tension so that it will not unroll as easy when a wind gust hits it?

Thanks

I would think you could, with a helper, run the slide out, disconnect the awning from the slide, manually roll it until there it was only about 1 turn from its max length and re-attach it. You have to be very careful and hang on to the awning at all time as it will be under a fair amount of tension to unroll.

Also thought about buying thus clamp. Not sure if it will work plus I'd have to drill a few holes in the rv.

Don't think you would want a clamp or lock on a slide out. It would be TOO easy to forget it was on and then try to run the slide out. Probably be a disaster in the making. JMO

Is that a cable tie wrapped around the tube? I see the clip through the end cap, but how does the cable tie grip the tube enough to prevent it from turning?

Thanks,

mx800, I would just tighten the spring and forget clamps & locks of any kind on the slide out. The regular power awning is a different animal and I would either put a clamp on it or a lock like I did or something similar. Saw one with a big hose clamp holding a picture hanger clamped to the end of the roller and an alum. screen door spring/chain (chain covered in plastic tubing) hooked to the bottom of the strut.

mx800,
what model coach do you have? I do not have an awning over the dinette/sofa. The only thing on that side of my coach (390by) is the slide topper and unless the whole slide is moving out, I don't see how just the slide topper can extend.

Gusting winds on that side while traveling and evidently not enough tension on the roller to keep it taut.

I don't understand what is going on here.

The Dometic Topper has an "anti-billow" lever that hits a stop on the wall of the camper when the slide is closed. It is supposed to prevent wind from unrolling the awning with the slide closed because the lever is jammed against the wall.

When the slide moves out the lever is pulled away form the wall and is allowed to turn with the roller. If the roller can turn with the slide closed, the lever is either broken or not adjusted properly; just like Youroo stated earlier.

I had the dealer tighten the spring on my slide topper. They said they got it as tight as they could It still billows up with a strong gust of wind. I don't see any anti-billow stops on mine.

What would stop this from happening is to keep the wind out. As you can see from the picture on my Berk is if you could put a piece of matching metal under the cover to prevent the wind from getting under the topper. It could be perforated so the water could drain out but not so much to let the wind get in.

Maybe blocking the wind from the end would accomplish it also. As an experiment, I would use some 100mph tape on the end. If it works, cut a pc of alum and secure it to the slide or somewhere. Have to agree with Herk, something is amiss. Do other mh like yours have an anti-billow fixture? If not, maybe fabricating one or modifying a Dometic one and installing it.

Just got off the phone with Dometic. Part #540 is the anti-billow device. I know I don't have this installed. I guess they forgot about it at the factory?????

Go to page 9 on the pdf. It shows the install.

Tater, mine does EXACTLY the same thing. I have temporarily secured it twice with duct tape while leaning out of the windows on the side of the road. (scary). One time I forgot it was still taped when I put out the slide. It broke all 6 pieces of tape that were keeping the topper in place, but it looked like nothing was damaged. I would be interested in a permanent fix for this. I have Carefree toppers.
