I recall sitting down with the dealer in Alaska and they were okay with any configuration probably cuz they had ample allocation. I wanted the running boards and tow hitch but at the time not the lockers. All doubts to my ignorance now removed. 
Seemed like a lot of $ at the time but that truck has happily served me well close to half my life now so great investment.
