The only thing I would be
The only thing I would be interested in is if Toyota could get the 3.5L V-6 to work smoother with the 6 spd transmission. Too many reports have them indicating that the transmission is not smooth, frequently gear hunting, and too slow on the downshift. Better yet, they should upgrade it to an 8 spd auto. The engine needs to be revved too much, and needs to be retuned to deliver better torque at the lower RPM's.
If the powertrain of the truck is lacking, the rest of these upgrades make little difference to me.
