It really depends on what you want to use the truck for. I had a 1993 Toyota SR5 and used it extensively on the narrow National Forest roads of the Colorado Rockies and was oh so glad I had a narrow vehicle with a shorter wheel base for the ability to turn it around in tight places and negotiate narrow roads with steep drop-offs. If you don't anticipate finding yourself in such places, full size is fine. In fact, I have a Silverado now as I spend far more time on wider roads, under less intense conditions.
