It has done OK on my 2013 but I am not real hard on it. Mine is a Big Horn with the liner option, so should be the same as what is standard on the Longhorn. I cut a hole for the B&W gooseneck hitch and found that it is 0.1" thick (a tenth of an inch). Many local places make them similarly thin to keep the cost down, but I would rather deal with a place to make it thicker. The factory liner is hard like Line-X, not "soft" like Rhino.
