The nose of your JEEP constitutes less than 6% of it's overall drag.

And even though the grille is recessed,all the radii around are generous enough to provide fully-attached flow there.It takes very little to be effective

Your problem is the horrific wake

You need some sort of boat-tailing to tame that drag.It's the only thing known to work in 95-years of research.
It could be something like in the lower image,a box cavity combined with extra cargo storage

This is the goose that lays the golden eggs.
