Sorry for the late reply. I am from Evans, GA. About 10 miles west of Augusta.
So far the truck has: Pop 'n' Lok tailgate lock, ARE Camper Shell wired for lights/power, Tonneau Cover (I swap them as needed), Heated Seats, Sound deadening in the entire cab, extra 12V outlet in the right side storage pocket. I don't plan on doing any engine mods or lift kits.
I haul enough stuff to keep it level most of the time. LOL! Actually, I may install some helper springs to help level out the trailer I tow but it's not a 'gotta have' yet.
The best thing I did was the sound deadening. It makes it an entirely different, and much quieter truck. I used duct work insulation (Lowe's/Home Depot). I did EVERYTHING inside the cab. I took out the seats, the headliner, the carpet, and all the door panels. The whole job took 6 rolls. It's 2 layers thick on the back of the cab and in the doors. The doors have a definite "THUNCK" now when I close them. I have a post about it with some pictures.
