Quoted for truth; here's a little pic I made up to help explain the difference:
Something to watch out for on C&C trucks if you're planning to put a regular bed on it. Not only will the rear end width bone you, the shape of the frame is different too so you'll be making bed mounts and possibly having trouble making the bed sit at the right height, AND...most C&C's are 4" longer in wheelbase than the closest regular truck wheelbase. There are SOME 1 ton C&C's that are the same wheelbase as the comparable 1 ton pickup but most are 4" longer.
