Bought it new, dealer installed lowering, 2" front, 3" rear, rides great, very fast, comfortable, easy access. Tricked out with $6,000 extras, snug top tonneau cover, air lifts, running boards, pin striping, etc., still get compliments on quality & looks. Never used 100,000 extended warrenty, however R & R differential at 158,000, and R & R radiator at 190,000. Otherwise just routine maintnance. Only disappointment is brakes, low pedal, too much effort, warp at drop of the hat, & early wearout until changed to drilled rotors & ceramic pads at 120,000...should have done this when new. With front end lowered, went through factory & top-of-the-line Big O with 28,000 to 33,000.
Leather/power interior very luxurious for a truck. Interior still tight, have to open window to slam door. After racing rotors & pads, brakes adequate. After up-grading to (one size over) Michelin "All Terrain" SUV tire, now get 55,000 to 65,000 miles.
Brakes not up to par, R & R fronts at 35,000, 70,000, 105,000, 160,000, 210,000, & ? 270,000...rears at 100,000 & 200,000... Trans filled new with Mobil One synthetic, after 250,000 still OK. Serviced engine every 5000 miles, started burning 1 qt,/1000 oil at 230,000, not bad...11 MPG overall.
