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.

Here's what you're up against
You want the tail to fill in the region occupied by the smoke (1st image),of the blue area in the other two.
You could use the 'Template' or Mair's boat tail
You can do better than a 'Trailer Tail.'
