I just picked up an 06 Reg Cab 4x4 5-sp manual with 65k miles for $10k. Everything looks great except it will need some new tires in the next few months and I'm going to toss on a new tensioner pulley to get rid of some belt squeak. Other than that I'll probably grab some synthetic oil, a new air filter, and new fluids in all drivetrain parts. Is there anything in specific I should be looking/aware of? I'm planning on spending a bit on the truck throughout the year and lifting the truck a few inches, getting some slightly larger tires, and a bumper/winch combo. Looking forward to posting up some pictures when I get into the truck and start with a few mods.
