It's big, it's long, and you're gonna love it.
 The double cab gives this truck a very long wheelbase which is great for ride comfort, but bad for turning radius.  Also, it makes the truck heavy, so fuel economy takes a bit of a hit.  Probably between 16 and 17 MPG on average.  Some of the radio controls became "wonky" or uncooperative with age.  If you're the "do-it-yourself" type, some standard maintenance tasks are pretty simple on this truck.  I replaced the serpentine belt in about 15 minutes having never done one before, and I also replaced the front brake pads and rotors in an afternoon.  (I tried to get the rotors turned, but they just needed to be replaced, so that ate up some time.)  For auto-mechanic ability, I'm probably about a 5, but these jobs were easier than I expected.
