Just like the competition, Toyota offers a work truck with few frills. For the Tundra, that's the DX, which comes only as a Regular Cab with a nice array of standard features: fabric seats, manual roll-up windows, CD stereo with aux input, manual a/c and tilt-steering wheel. Tundra DX models wear P255/70R18 tires. Options include three basic packages: SR5, Cold Weather and Tow. The SR5 Package comes with power windows/doors/outside mirrors, cruise control, upgraded fabrics and chrome bumpers/grille surround. Cold Weather shoppers will want to check this box as it includes heavy duty battery/starter and heated power outside mirrors. Same goes for tow customers: In addition to the normal tow elements, models with the 5.7-liter engine get manual extendable towing mirrors.
