Writing to ask if anyone else has had issues with their DualLiner bed liner kit. I did a lot of research and that is the brand I eventually chose. Anyway, I installed the thing yesterday only to find I could no longer close my tailgate. The thick rubber mat seemed to be approximately 1/4" too long. I called DualLiner and they recommend waiting a week or so for all to "settle in". I have been in the bed kicking the thing forward (towards cab) but now see that the mat is held from moving forward by the side panels (up tight to wheel well). I provided measurements of the mat to DualLiner and they advised my liner should actually be a full half inch longer! I considered trimming to fit but that would destroy the factory edge and would not look very well, especially considering the money they get for these things. Any help would be appreciated (but I saved the shipping carton just in case). Thanks much! Oops...forgot to mention; 2015 F-350, Long Bed, Regular Cab.
