over the rail box
I've seen a low profile over the rail diamond plate box at a truck accessory's place called Earl Owens in Sherman TX. But at the time I was having nerf bars installed, and did'nt question them about the fit on the 03 Dodge. I did like the looks of it an was wondering if it would be ok to use looking at getting a 5ver in the future. I did not measure it, but looked like it only stuck over the rail a inch or so.
