I have 2005. I do a lot of wakesurfing so having the mid gate is real handy for some of the longer boards.
It's nice to have the seating for five when you need it.
I'm getting over 16 MPG, about 11 towing.
A good truck and a cool looking truck. If the cool factor doesn't do it for you then get a regular 4-door truck and save a few $.
