Can I use tie down bunk boards when I replace old rollers with bunk boards? I dont know what tie down bunk boards are. This is only an old Sea Nymph 14 footer on a little dude trailer. I dont know why they used rollers. They're old and rusted and I think loading will be a whole lot better with bunks. I also dont like the weight distribution on these rollers. The boat seems to bounce too much. Thanks
