Crossing state lines, with parts

No Ford smaller than an F-650 has a GVWR over 26,000lbs. (And many F-650's, including the one I drove, are under 26K.)

Maybe I wasn't clear enough... I was talking combined, same trailer (14,000), but the brand new F350 put him over 26,001. Where the old truck, (mine) was 11,000. (combined 25,000)
So, when he bought the new truck, he didn't realize he was overweight, and then needed a CDL.
