I like the newer Tacoma design, but I just can't get excited about that powertrain. Sound like the 6spd auto would be better off if the motor did make more lower rpm torque. I often lock out OD on my 4.0L model when I'm in town, as it is programmed to shift into OD (5th gear) at pretty low revs. It's a simple side-to-side bump on the shifter to have OD or not. Toyota should look at a big 4cyl with a turbo if they want better fuel economy than the old 4.0 while still making good torque. Modern single-turbo fours can easily make around 300-350ft/lbs in the useable part of the rev range.
