 I traded in my 06 Tacoma Double Cab Prerunner longbed w/TRD Sport Pkg.  I  chose the Crewmax w/5.7 6AT SR5 because I liked how smooth it drove, and I wanted the interior space to accomodate my family on road trips from Vegas to Southern Cal.  I love the seating position in the Crewmax.  In the Tacoma, the seating was comfortable, but you had to sit low like in a sports car.  There were also no option for any kind of seat height adjustments.  I also like the power on tap when I need it, and the braking power.  Turning radius is pretty tight for a truck this size.  It's too soon to see MPG, but I hope to get 16 city.
