Well hell now days trucks come in 5' beds, 6'6" beds, and 8' beds.
I prefer a 6'6" which used to be a short bed but now I guess it's a standard bed. If it won't fit in my truck without/with the tailgate down I put it on the trailer. It will take lumber and plywood up to 4'x8'.
I like the shorter wheelbase just for turning around in the woods. If I had a dollar for every truck I've smacked right in front of the front wheel against a tree while out in the woods I could buy a new truck lol.
Having said that my current 4wd is an extra cab (no crew cab) 6'6" and my diesel is a extra cab as well 8' bed.
