Rear window vents

[EricH]

Do you guys drive down the highway with them open and your four windows down?
I can see the vent windows slightly wobbling through my outside mirrors and wonder if they are strong enough to handle such high speed turbulence.

Open. It reduces the cavitation a lot. Plus the passengers in the back seat don't have their hair flown around as much.

They're strong enough.

the ones on my excursion are huge...although i had one fall off on my '04 i never had an issue with my 00 or 02 up to 100mph.

Thanks guys! I just wanted to make sure there was no fine print in the 2 mega-manuals that came with the Expy that stated "Close rear vent windows at speeds above 55mph".
