Yup go for a test drive...or if your dealer will let you take the truck for a day or two even better. Like mtofell1, the more I drive the truck the more I am impressed with it. The only remorse I have about the purchase is that I didn't get more options. I love the truck and would buy it again without a second thought. It handles my camper with ease, the power is great, brakes great, brake controller is spot on, transmission is awesome...there is nothing that I don't like about the truck.
I'd love to hook it up to a big 5er or loaded gooseneck trailer and see how it does. Waiting for ib516 to get his so I can hear how it does with a 5er!
