The Dual Liners Zero Skid floor can be rolled up to allow you to install your hitch while you are towing your fifth wheel . Them when you get to the campground you can pull the fifth wheel hitch out and roll the mat back out and tuck it into the perimeter channels so it doesn't go anywhere. With a spray on it seems that you either have the rails unfinished or underneath the rail is exposed. We recommend you go with a under the bed mount hitch as well. That way there is no obstructions at all in your bed. If you need any technical help feel free to email me at todd@dualliner.com or check us out on the web at DualLiner Truck Bed Liners, the BEST Bedliner in the industry! .
