So been having a big discussion on a couple of Van facebook sites about Big Chevy vans and their aerodynamics.

So I am wondering have anyone done any looks at these vans??

I am talking about G20/30 vans like my 93 and a 2017 Express van.

I am also interested in the Stock and with the great ground effects and raised roof.

Funny thing about my 93 Custom is that the ground effects seem to work, as my Van is NO LONGER pushed around by big rigs, either passing them or being passed by them. A stock body van is buffeted badly but big rigs, nearly pushed off the road…these custom vans (at least mine) are not.

So I wonder how bad these vans are aerodynamically??

And what (IF any) can be done to make a real world improvement.
