OK, so i've had my Ram for a few months now and love it. One of the only issues i have is with the drop in bedliner the previous owner put on. Its perfect if i need a load of mulch, etc but not so good for smaller things. What are you guys doing to secure cargo back there. Its so slick things want to slide all over the place. I'm planningt o pull it out one day and get a pray in liner but for now would like to find a good way to get things secured. any suggestions? There are two slots on each side that look like they could hold a 2x4 but that would only help with stuff that just the right size. thanks,
