Truck is easily worth 40K, you smoking crack. The only light on the dash is from an aftermarket tire pressure sensor. Grumpy much to bomb a person who is trying to sell their rig?
My 1500 diesel lasted 9 months before I went up to a 2500 diesel... the 1500's payload just got eaten up so fast it was scary. 3.0 Kings and 35's and I haven't looked back.
