On the 65, I think the cab mounts are different (although the 3/4 may be the same), the rear leaf springs are different (ditto 3/4), the dually dif (ditto 3/4), and cab and chassy option (ditto 3/4). Like I said, I think.

But the real reasons they are different are;
Cooler daily driver than the 1/2 ton.
More practical daily driver than the big bolts.
Mine is a 1 ton.
