My truck has very nice floor mats with snap out carpet, so no need for the floor mats. Not sure if yours will be equiped the same.
I love my AMP bed step. Makes it easy for even short guys like me to climb into the back of the bed.
Very happy with my aux fuel tank, but I know some aren't into that.
Some sort of a bed cover would be nice for when you don't have the 5er.
Tinted windows
B & W Stow & go hitch for when you need to pull a trailer
I also put on a bright set of back up lights. B&W that go on the receiver draw bar.
Does the power door lock work the lock on the tail gate now? If not, there is a kit for that.
Have fun with the new truck!
