I fit into this category of irrational love. All wheel drive, five speed standard, nice four cylinder turbo, off road capability, hauling capability, seating five, low center of gravity-jack of all trades! (I know, mastering none).
There is a woman with one near me who I strangely often see outside the local wal mart, and I may be getting creepy in complimenting her car each time lol.
If I were you, rather than a cover, I would buy a used/old shell from a pick up. Searching a bit on google is showing
749.99 for a Baja tonneau cover, I see a few A.R.E. caps, but no prices. The Z cap is what fits.
I would search craigs list, and make your own.

You can always find one, and build it into what you want. If it were me, I would have to drop the tailgate, and make it into a boat tail, or as close as you can. Building it just to the edge, or what you feel right with. I often see truck caps for $50 on the side of the road, might be an option for you. Definitely the cheapest way to go.
This site had a nice build for a flat one, do it yourself:
