Weight removal in a vehicle this heavy is nearly irrelevant. You wont be able to remove enough to make a difference.

A hotter t-stat and synthetic rear dif fluid made the biggest changes for me.

NO TONNOU COVER ! Not a flat one anyway. It kills the air bubble in the bed.

I recently added a tool box and am waiting for mor data to see what it does, since yours has a computer let me know if you test this out.

On a borrowed truck i guess major aeromods are out? An aero shell might be in order .
