Only accessory I'm currently looking for is an undetectable, invisible radar detector. Virginia remains the only state I can't use one and I live here.
Don't tow often enough to need the F150 style mirrors.
Put good mud catching floor mats in the truck the day it came home. Right out of my '07. Had to buy new mud flaps though. Upgraded the headlights to HID (low) and LED (high) as well as LED backup lights. The rest are fine. Getting close to the time to check the catch can level.
Still discovering stuff about the truck that's different from my '07 like the headlights coming on automatically with the wipers. Lots of stuff is completely unnecessary such as the seat/pedal resets and the power 3d seat. I don't recall having it up more than a couple of times.
