Quoted:
I don't understand the love for leveling kits on pickup trucks. The rear is higher than the front because of the vehicle's intended purpose (hauling cargo) so that it levels out with extra load.
Form > Function for those who like them. Most of the kits wear out ball joints faster too as a FYI.
If it were mine I'd do the following
Sams club all weather mats ($25-50 for a set of 4. Have had mine for 8 years great value and I love them)
Projector headlights and 5K HID's ($500ish depending on if you do the conversion yourself, have someone do it, or buy aftermarket lights)
LED/cathode under dash lighting ($30ish, get what you need from oznium.com Wont have a vehicle without this anymore. Great for finding something you drop while driving at night)
RIGID or knockoff LED light bar mounted to grille or bumper ($100-500, better output than off-road lights and less draw)
HD Bumpers front and rear with sliders if you're gonna do any serious wheeling/off-roading (figure $3K here...maybe more)
rear helper air bags and tow controller (if hauling/towing heavy things often)
