I went 4x4 for a few reasons.

1) I live in a very hilly area and need it in the winter.
2) I pull a utility trailer to the dump, which can be pretty messy.
3) I use 4WL it when pulling the trailered boat out of the water.
4) I occasionally off-road.
5) I don't want to get stuck anywhere.
6) Buying a 4x2 truck is like buying a 4 cylinder Corvette.
