Truck was purchased from MCH Kenworth in Oklahoma for $42,000 in Sept. 2015. Head gasket and spacer plate went out the first week after getting it home, or was out when I bought the truck. Paid $7400 to have it repaired. At that time decided to have ECM delete, up horsepower 625-$3500. Put wet kit on-$3500. Replaced rear U bolts in rear end-$800. Front axle rebuilt, king pins, seals,brakes, all wheel alignment, new steer tires-$3000. 24.5 rims, low pro on drives, 11R on steers, 90% steers, second axle 20%, 3rd axle 95%, flex air suspension, 3.36 rear ends, 13 speed transmission, acert c15 cat, new power divider plus gears-$600, 70 inch bunk. Everything works, tight truck, pulls awesome, rides nice, drives straight. Purchased the truck with 810,000 miles, now has 872,979 miles. I have $60,800 into this truck. My wife says she"s going to divorce me if I don"t quit doing the trucking thing. Enough said.
