I Purchased this truck in 2007, i have added a 2 1/2 inch tuff country leveling kit, 35X12.50 Toyo Mudders, and Ultra-Goliath 18" wheels. It also has a set of firestone airbags. I have had a couple different programmers But wanted all banks products- Banks sixgun tuner w/speedloader, Power PDA, Banks monster exhaust, with the cat deleted, and Banks ram air intake, For now, plan to have all the products Banks makes for it.  I love to drive this truck and it sounds great when i step on it. I use it for everything, From pulling my 27 foot camper to the mountains & hunting, to just driving it around town. My wife is convinced I love my truck more than I love her......I think its a toss up!!!
