There will be 5 different beds, the deluxe which is the cheapy single wall bed, the SR5/standard bed which is the double wall two wheel drive bed, the SR5 four wheel drive bed that has molded in flares that cover the larger tires (some extracab 2wd also have this bed), and the long bed for 2wd and then the flared model for 4wd. It doesn't matter if it is a Standard or extracab the 6 ft. beds are the same.
