Don't get me wrong, I don't dislike aero-trucks, I appreciate all designs. I see trucks as an art form.
Some of the new designs have me scratching my head. The T700 is too slab-sided. The 587 and 386 have the nameplates crooked. The Cascadia has those awful "I give up-don't shoot me in the back" spot mirrors. One of the big problems the truck manufacturers face with making an aero truck is trying too hard to stick with the traditional blood line. The result is a mixed bag of traditional and aero that sometimes doesn't work. (think the 1990 Cadillac Sedan DeVille with the composite headlamps and cladding on the body- the original look became blurred and muddy). KW and Pete have been using the same basic cab for 25 years which really limits how they design aerodynamic parts around it. Rounded windshields and visors can only do so much. Navistar and Freightliner broke that pattern with Prostar/Lonestar and Cascadia. Mack has been slowly tweaking their aero trucks. Nobody has mentioned Western Star in any of this - the WS designs are all areo - with air cleaners stuck on the side and a squared grille. Volvo has always had the aero design, their foray into the long hood war was a lost battle before the first shot was fired. The market was gone by that time. Truck manufacturers have tried in the past to kill off the long hood models - forcing customers to their other products - but the market has demanded the long hood remain. Even as recent as 2 years ago the 389 was supposed to end, but dealers and customers demanded it remain - so it does until the market for it eventually dries up.

With the huge demands on the manufacturers from the upcoming EPA MPG standards, the manufacturers will be pulling out all of the stops to smooth out the bumps and chunks in the truck designs. We will really see some radical designs in the future.
Funny thing about aerodynamics - in the 70's drivers were buying big bulky add-on air shields and foils and other devices to save fuel.
Back then all you needed for a custom truck was cool paint, nice lettering, some lights snazzy interior.
