i personally dont use a truck like a truck lol. only truck like things mine does is pull heavy equipment for my dads company when the POS 6.0 is out of commission lol. over the rail bedliner is much more functional, and since i dont use a trucks bed...i think under the rail is MUCH cleaner looking. my old truck came with over the rail i couldnt take it off if i wanted because the plastic drop in rubber the paint and left a nice line where the liner stopped...with spray in you wont have this issue, nor the choice of removing it lol.

 

nothing yet...but im still new to the ram game im sure ill have my time
