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.

Interior Features

The Tundra is a comfortable truck with a friendly interior. Front-seat roominess is competitive with other full-size pickups. Toyota claims the Tundra provides more front legroom than any of the domestic pickups, though only by about half an inch; and the Nissan Titan has only a tiny edge over Tundra. The others, especially the F-150, offer more hip room than the Tundra, however, and owners notice that.

The Double Cab is slightly roomier than the other Tundra models. It offers an inch more front headroom and a fraction more front-seat hip and leg room.

The 60/40 split-bench cloth seats that are standard in most models are welcoming and supportive. Double Cabs come with bucket seats up front, rather than the split bench.

Climbing in is easy, though the two-wheel-drive model seems to sit higher off the ground than other two-wheel-drive pickups. The Tundra feels tall in the saddle, giving the driver a commanding view over shorter vehicles.

Accessory switches are concentrated in the center cluster for easy operation. The fake wood on the dash is dreadful, but the instruments are straightforward, with a big tachometer on all but base models. A center console with four nice, big cup holders; dual map pockets; and covered storage is shared with the Toyota Sequoia SUV. Its lid holds a pad for note-taking, but it felt flimsy when we tried to use it. Double sun visors with extenders are useful at sunrise and sunset.

Access Cabs add interior storage space and the ability to carry two more passengers. If those passengers are adults, however, the rear seat is a short-term affair. The Tundra does not have nearly as much space in the rear compartment of its extended cab as the other full-size pickups. And the rear seatback is vertical, forcing occupants to sit bolt upright, uncomfortable for traveling any farther than the neighborhood restaurant. A far better use for the extended cab is carrying dry cleaning, groceries, briefcases, outdoor gear, or anything else that should be shielded from the elements. Unfortunately, the rear seat takes up a fair amount of room. The seat bottom on the split bench can be flipped up, but the seat doesn't fold completely out of the way, nor can it be easily removed. Some of the domestic extended cabs offer much better versatility.

Double Cabs, on the other hand, provide genuinely useful space for adult passengers in the back seats. Its 37.5 inches of rear-seat legroom make for comfortable accommodations, though Tundra's back seat still doesn't have as much space as in the Nissan Titan, Ford F-150, Chevrolet Silverado or GMC Sierra. But Tundra's rear seatback reclines at an angle of 24 degrees, adding to comfort. Each rear seating position has a headrest and three-point safety belt. Rear-seat passengers also enjoy their own heating and air conditioning outlets, and optional audio and DVD entertainment systems. Tundra Double Cab also offers the segment's first vertical power-sliding rear window. At 750 square inches, the Double Cab's rear window offers more than four times the open area of the manual sliding rear windows in the Regular Cab and Access Cab models, making it easier to access the bed especially important with a canopy. When the Double Cab's 60/40 split rear seat isn't occupied, it folds and tumbles to provide lockable, weather-tight storage space inside the cab.
