No up-grades really to speak of as of yet, not counting the Garmin Ique GPS unit, the extra set of D-rings in the bed, the tonneau cover, and the custom install on the brake controller. So ok maybe there's been a few In the works possibly, URD CAI, URD maf callibrator, URD Y pipe, and TRD exhaust...
hey, does your truck pull that trailer pretty good? Do you have the auto or the manual? Also what kind of tonneau cover do you have? looks similar to what i would want to buy. Is it just velcro?
