I have a lifted dodge with cummin's 2500 with 37's and it rips. Haven't had any problems with it yet, and I also have a dually that I pull my 15,000 pound fiver with along with a 16 foot trailer behind that. Kinda looks like a train goin' down the road, and had to get a combinations license. It just depends on what you are planning on doing with the truck.............. :biggrin:
