Have you been on performacnetrucks.net???

It's the sister site to this geared for trucks.

No matter what you do, having the PCM reprogrammed will make a huge difference over the feeling and drive ability of the truck.

The biggest bang for the buck will be a tune.

Drop in truck cam would be real nice and some you don't have to tune for, but I'd highly recommend you do, will be night and day with/without a tune especially with the cam. (the tune applies to a lot of things... throttle delay, torque management, shift points, trans line pressure, rev limit etc etc)
