Lots of time in 4 wd mostly in Mammoth Lakes, eastern Sierras, Death Valley, backcountry all around Carson City area. TRD is stock and VERY fast just the way it is. Currently running new Bridgestone 265/75/16 LT Revos which have much better traction than the Duelers I used to run. I need replacement front shocks but having a hard time coming up with the $$$$ for the Donahoes I ordered. I put Bilstein 5100’s on the rear.
