Myself I wouldn't buy a Dodge or Sterling 4500-5500 for one Dodge is on the verge of bankruptsy and Sterling is no longer. The trucks have been in the market for a year. There isn't very many of them on the road. The 6.7 doesn't have a flawless record thats for sure. Your really taking a chance on buying one. I would be asking the Dodge dealers in your area if they will work on it before you buy one. You might be getting a good deal but what happens when the truck breaks down on the side of the road and nobody will touch it.
