I've had mine less than a week. It's exactly like yours except mine came without the tailgate step that I ordered.
As far as mods, I got the dealer to do the mid perch before I drove it home.
I have a short radio antenna ordered. I plan to get my windows tinted soon. I need to order a tailgate lock, but haven't decided on which one to get. I'm also considering a bed cover.
I remember reading a thread about removing or covering the orange reflectors on the mirrors. I'd also like to do that.
