  1. The wheels have to be far enough out to make room for a wide enough bed. Making the whole vehicle wide to fit would likely increase air drag.
  2. Fuel consumption rules are based off of wheel base width and length. So it would make sense to make a smaller truck and find ways to make the wheel base wider at the same time to make it easier to meet CAFE standards.
