Just so y'all will know. In 2004 SuperCab rear seats grew by more than half. they are no more the tiny rear seat of the 2003, and older.
Here is the F150 seat specs.
......................SuperCab................SuperCrew
Shoulder room.........65.8in....................65.9in
Head Room.............40.3in....................65.9in
Hip Room..............64.7in....................64.7in
Leg Room..............33.5in....................43.6in
So the only real difference is the Leg room. Judging just by my truck. Unless the rear passenger is really tall. There is enough room for a trip to town. And for short people like my family. There is plenty of room, even with 2 car seats back there .
But again. the real downside is opening the rear doors in parking lots.
As for the resale value. My truck is 13 years old, and I have no plans to replace it. So the resale value means nothing to me really. however. I have been offered some pretty good money for it, Because it is in such good shape.
