2007 Toyota Tundra Double Cab SR5 4dr Double Cab SB (4.7L 8cyl 5A)
Great truck
 I've driven my Tundra thousands of miles, towed a trailer across the US, and generally been very happy with this truck. I would definitely buy it again. This review is actually for the 5.7 V8 engine, not the 4.7L engine. Lots of torque, good pulling power. The 2007 truck as well as its later brothers excels at pulling, but has a wimpy payload compared to other 1/2 ton trucks. If you want to mount a camper in the bed, you'll need to beef up the springs and rear suspension with an after-market supplier. Comfort and amenities in the 2007 were good -- nothing spectacular. The brake controller and rearview camera were add-ons, something that Toyota has now addressed in the new models, but essential if you plan to tow anything larger than a small fishing boat. Adjustable drivers seat and heating/cooling system work admirably well. When I traded this truck, it was still in great condition, and had no mechanical issues.
