New Super Duty coming next week. My first truck since a well-used '49 International L-110 several decades ago. Dog Conveyance System will be either Truck Vault type drawers with crates or a topper mount of some sort. Questions-------- Should I get a sprayed on bed liner such as Line-X or Rhino Lining put on now? Would this make a difference when the DCS is eventually mounted,particularly in terms of bed width? If a spray-on bed liner is installed, what is the best brand?
