Our Mark LT did not come with a bed liner. I found a really good deal on a brand new 5.5 liner. But the seller says its for the 2015+ year model. My question is since it is the same size will it just drop in? Thanks

edit: there is also one from a 2013 year model; this one is also a 5.5 bed liner.

 

I would stay away from anything past 2009 model year. The bed floor could have different stampings. If you have a cover may I suggest the Bedrug, awesome durable liner and turns the bed into a trunk like space..... very nice!
