I put a Backflip full tonneau cover on my 2001 2500HD extended cab short (6.5') bed. With the 8.1L engine, Allison Automatic, 4.10s, 4x4, 285/70R17 Michelin M/S 2 on factory 17” alloys, I can squeak out 14MPG with very conservative mostly highway driving. Previous best prior to tonneau was 13 MPG, but that isn’t A-B-A so take it with a big grain of salt. Around town is 11.

Thanks.I should not have inferred that all the drag reduction was linked solely to the tonneau.I went back and 'accurized' my comment.
The Avalanche/Escalade/Ridgeline must get a little benefit from their cleaner flanks.And the lofted the bed rails should reduce the vortex in the bed.
Some of the concept trucks have very high rails with respect to the cab roof.
It's a good thing and perhaps truck buyers will embrace the 'difference.'
