I would like a tailgate/rear bumper design
that mounts the spare tire in some new innovative way.

Ideally a new design that replaces 90% of the weight of rear bumper and lets the horizontally mounted tire absorb low speed bumps.

I still want an unimpeded Class 4 trailer hitch mount

I want the spare tire easy to get at but still theft secure as practical.

I want some aero improvement as a bonus

Let those engineers spend free time designing specs for the wants listed above, and make it look good too.

On second thought,
make the rear look mean and menancing
so that cars wont tailgate too close to the rear of the pickup....
