I bought a used '06 in '08. I wanted a V-6 for milage (traded in a Jeep Wrangler) but the V-6 is a dog. It won't get out of it's own way. The rear end is super light and on rain slicked roads you really need to watch the break away factor. That could also be because of the crappy Good Year tires the truck came with. I'll be upgrading the tires to Michelins very soon. Suspension is extremely soft and bouncy, almost like driving a '70's era Cadillac. The bed could be a few inches longer but it works for what I need. I can put my Suzuki RM in the back straight on with the gate down. The mpg is decent, not great, not bad. So far, I haven't had any mechanical issues.
Exterior looks, size. Small tucks are too small and full size are too big. This one is just right. Rear seating is good for adults. Rear doors open wide. Ample storage.
Stiffer suspension. Better tires. More power out of the 6.
