The automakers consider pickup trucks to be typically a 2-door sedan sans trunklid.With a full tonneau,a truck would essentially react to mods the same way as a notchback.
An aeroshell would place it as a fastback.
*If you look at the 1991 GMC S-15 Syclone LSR (permalink#7,14,etc..) this is a Cd 0.315 truck,lower than a Corvette of the day.
*wiper delete
*mirror delete
*California aero package:bumper fascia/airdam,fender flares & rocker skirts
*lowered,Bell Tech dropped spindles
*lengthened body 12.2"
*widened body 0.8"
*MOONs
*1/2-tonneau

This is the T-100 at Bonneville in 2012:
*sealed bulbous nose fascia/with integral airdam/grille-block/plex. headlight covers/turn indicator covers
*front wheel opening gap reducer (driver side)
*articulated front wheel skirt (passenger side)
*hood blister with side Plex. diverters
*full-depth rocker panel extensions
*aspirated full-coverage wheel covers (for the road)
*rear wheel skirts
*compound-curvature aero shell with stinger
*30-inch boat tail
*Front wheelhouse trailing flow blenders
*tail light Plex. fairings (off)
*Belly pan (partial)
*rear wheel trailing fairings (off)
The T-100 is estimated at around Cd 0.16 from the MPG data (362,000-mile database).With the missing bits she would do 32 @ 75-mph,up to 37 mpg @ 65-mph.I'll try for the Darko Technologies wind tunnel in September if my world doesn't explode.
