Is there any way to bring the tail end of the vehicle to a point like the trailing edge of a teardrop?

If you've seen the template from Darin's Project: making a permanent Metro Kammback,you'll see the length necessary to completely eliminate profile ( pressure) drag.Not very practical for daily driving.--------- The trailer project I'm targeting for September will be a way for me to investigate a "full" tail.Since we expect "length" with a trailer it's not a "hardship." By making the trailer a "boattail",it provides a safe way to investigate the inherent gains possible by a full tail.---------------- Since I like to camp anyway,by extending the length,I get a full boattail and a place to "live" out on the open road.The moveable gap-fillers between the truck and trailer face provide a complete flow support surface,from the T-100's nose,to a point 12-feet behind the truck.------------ The wake will be reduced from 29 square feet,to about 1.5 square-feet,to accomodate the rear license plate and taillight pods.Profile drag will be virtually eliminated.They'll be a little skin-friction penalty and increased rolling-resistance from the trailer and its axle/wheels/tires.I got 50-mpg pulling a trailer behind the CRX and it was nowhere as streamlined as what I'll achieve with the "Viking" hull-based unit.From the equations,the rig might see 40-mpg HWY,and 36-mpg Interstate.No telling 'til it's over,hence the premise of the project.
