Instead of the pressure flowing around the body, the awning tube creates a low pressure area on top. I'd love to see a study on that to test my hypothesis. It could explain some instances where drivers have lost control.
one of our unit members had his 30' Airstream go airborne when he attempted to pass an eighteen wheeler loaded with hay bales. Witnesses told him that his Airstream simple lost contact with the road surface and was pushed off the highway. There are serious implications.
this thread is perfect timing as i leave for a vintage rally this next tuesday in chama new mexico, about a two thousand mile round trip for me. i'll be careful to watch for low pressure surges around the zip dee awning tubes and loosing contact with the highway. you don't mention it, but did the fella with the flying 30' AS, always cruise down the hiway with his Zip Dee awnings deployed? or was he able to launch by the simple nascar backdraft / hay truck slingshot method? kevbo

I think that in order to get fully airborne you have to turn your dump valve towards the rear of the trailer. Use a Pizo igniter with a loooong wire to your tow vehicle. Then just as you start lifting you click the Pizo which ignites the methane in your black water tank. Gives you the needed extra boost...
That's what I need - something ELSE awning related that I can worry about that can create awfull peril. Now I can worry about my rolled up awnings levitating the trailer every time I see hay bales! Thank goodness the one on the roadside is smaller diameter than the one on the curbside. Just think, if I were in the FAST lane, I could get the trailer flipped over.
This hobby is not just expensive, it's also plum DANGEROUS.

Gosh, if only I knew who is doing the teasing I might be able to laugh with you. I've got to get me an anonymous identity so that I can join in the fun. "Friends tease, strangers mock."
i wonder just how many more airstreams we have to loose. the Zip Dee "effect" must be addressed. why hasn't anyone pointed this problem out? hard work rarely pays off, but in this case, science does.
