Wonder if a deep air dam and trailer skirts would help at all on a van or sprinter.
I've often thought of that...then I get thinking snow banks and some of the crap we get into....
Nothing wrong with a steady 22 MPG's and then throw in an occassional 24-26 in this old beast almost 6,000 lbs empty.....at 55 mph and 2500 lb load STILL get 23-24....Screw North American slop buckets...LOL
