A short bed crew cab is about the same length as a long bed ext cab. If you do not really need the bigger seats in the rear, an LB excab may be the better option for some of the reasons said above.
THen one needs to look at how the steering is on the truck you will buy. At one time, Fords LB CC could out turn a GM IFS ext cab with a LB on it, due to it having a better bigger angle the tires turn away from center. My Navistar with a 188" wb has a tighter turning radius than a typical 150" WB pickup, including the Ford, as it has a 54* turning of the wheels, vs 45-50 for pickups.
