Had one 10" in a mazda standard cab. The 10 was behind the driver side of the seat, and the bax was ported in the lower corner facing the passenger side of the cab. It rocked, to balance out the look, my amps were flush mounted on the passenger side.
Not sure of the internal volume, or tuning frequency, but that would depend on the sub you chose anyway.
The two 8" box above would be similar, and should sound nice if built and tuned correctly.
Of course you could always buy a prefab made for the truck, but won't sound as nice in the long run.
