Just found this site today. I have a 2003 Tacoma SR5 V6 5-speed Manual 4WD, which I bought new as a third vehicle, so miles are low at 17,500, as of Sept 2009.
Right after I bought my truck, I installed fog lamps, Linex bed spray, Truxedo bed cover, and a few bed holds. The truck is pretty much stock, and it just passed the inspection for the frame rust perforation (likely to be spray coated as soon as the local stealership calls). I do most of my own routine maintenance.
I plan to put Firestone Destination A/T tires on this month (appt on Sept 21). I've never liked the stock tires; they are terrible in rain and snow, even with 4WD.
My primary vehicle is a 2003 VW Jetta TDI diesel with a 5-speed manual. I've done a lot of work on my Jetta to enhance its HP and torque. If interested, just click the link.
