The Tundra Double Cab looks bigger and brawnier than the Regular Cab and Access Cab models. That's because it is bigger, not only longer in wheelbase, but more than three inches taller as well. Around back, Double Cab models sport unique taillights. At 74.3 inches, the Double Cab's bed is just a half-inch shorter than the Access Cab's. The Double Cab's four doors are traditional front-hinged doors.
Access Cab models have four doors, but the short rear doors are hinged at the rear and open opposite the front doors. As with other extended cabs, the doors on the Access Cab will bang into one another if you close the front door before closing the rear door. Fortunately, the inside of the rear door is padded, so this isn't a big problem. Handles for the rear doors are conveniently located on the outside, whereas most domestic pickups with extended cabs hide the handles inside the door jams. Unfortunately, the handle design isn't the most comfortable to use.
Regular Cab beds stretch over 8 feet, but the Access Cab's bed measures only 6 feet 3 inches. That's a few inches inches shorter than the medium-length bed offered on a Ford F-150 Supercab, but 7.7 inches longer than an F-150 Supercab's shortest bed (which still requires a wheelbase 4.4 inches longer than the Toyota's). Toyota's bed is 5 inches shallower than Ford's, 2.3 inches shallower than the Chevrolet Silverado's.
Double Cab beds are only about a half-inch shorter than the Access Cab's. The Double Cab's bed is 20.7 inches deep, 3.5 inches deeper than the beds of the Regular Cab and Access Cab. That makes it slightly deeper than the Nissan Titan Crew Cab's bed, though still not as deep as the Ford's.
