You are lucky to get a copy of those manuals at all. When I bought my slightly used '12 in early '14, no manuals came with the truck. Dealer wants big $ that I didn't want to pay, but will now have to pay. I only have 54k on the truck now, but am getting tired of getting a "recommended service" list each time I go in for an oil change that lists darned near $1k in recommendations. I have no idea if they are feeding me a line of garbage, or if the recommendations are true to the owners manual states. I am not afraid of paying for good maintenance, just not wanting to be taken advantage of by not being an informed owner.
