flip pac flapping noise

Was camping in the desert and the wind came up, FLAP-FLAP all night long, came home and fixed it= brian

Yep the flippac can be quite loud in strong winds, looks like you found an answer.

What are those things along the side of the lid that it's attached to?

marine loops, I pick-up at local marine store.
thanks=brian

Great idea. If you used stretchy straps or shock cord, it would help gather the top inward as you fold, no?

loops

I picked them up at west marine , I believe the name is (footman loops) they are bimini top strap holders.

I think the flapping is coming from the center roof vent. As a strong gust of wind hits the tent the internal pressure is released through the vent. It's a good design as it stops the tent from deforming as it's pushed by the wind.

As you found out the billowing can be noisy, and your ingenious solution makes the tent much quieter. How does the strap effect the ability of the tent to vent through the center roof panel? If it does severely restrict air escaping through the vent what effect would a heavy gust of wind have on the tent? Could you get the same effect by adding more cloth tabs between the center vent and the walls?

What effects will stopping the release of internal pressure have on the tent, and where will those stresses now go? Are we looking at quite restful nights or risking having our tents ripped off our shells?

Wind noise

Here's how I solved our wind noise problem:

The truck will bounce around a lot in a high wind, due to the "sail"
effect of the top, and the top-heavy weight of two occupants in the bed.
It is disconcerting and keeps me from sleeping well. There does not
appear to be any structural problem, though I certainly would not leave
the top up in a hurricane! By "high-wind" above, I mean the kind that
blows down ordinary umbrella tents, etc. Maybe over 20-25 MPH ? You
also have to be carefull to point the truck into or away from the wind,
if there is anything other than a light breeze. The fabric top has a
separate top flap that covers a full-length strip of netting. It is
designed to lift slightly in a breeze and increase air circulation. It
works very well when the conditions are just right, but if the wind is
too strong and coming from the side, it will flap and drive you crazy.
There are a couple of velcro tabs to secure it, but they are inadequate
for all but the most gentle of conditions. After putting up with the
racket for several years I bought a tube of "Liquid Nails" project cement
and glued the edge of the flap down permanently all the way around.
Works great and is a huge improvement. (Note: The tent is now made with
more velcro tabs which might solve the flapping problem). We have found
that the best results in wind are to face the back of the truck into the
wind, open the rear window & close all the others. This "inflates" the
tent and stops all flapping.

If you noticed I only strapped down the part over the bed as you stated a restful night is important, Next time out and theres a wind I'll let you know if this works.
thanks=brian, PS how do you recommend installing the rain flap?.
