THANK YOU for posting this
In regards to shape/size/length... How would one determine this for their particular vehicle? I see mention that it would be based off of 50% frontal area wake... Can a fella get a translation for this? I know you guys are wicked smart with this stuff, but I'm not so much
Also, I see you based it off the bottom lines of the hitch for your underside... Did you intend for there to be a rear diffuser to meet with this design? it seems that dropping below the rear bumper would create more drag/poor air flow?
I had planned on basing my design off of the aero backs on the big rigs trailers, rather than an actual boat tail. It seems that yours follows this train of thought as well?
Any feedback you or ANYBODY else can give me would be awesome! I fully intend to build something for my Mountaineer. Spare tire, recovery gear, emergency gear, all tucked away inside it.
