I have a 53/5100 COE with the 110" wheelbase. I'm pretty sure it was used in its first life as a road tractor, transporting cars. I love the short wheelbase. Still can't get it in the garage because the cab is almost 8' high and my door isn't? Mine is now fitted with an 8' dump bed. If you put a conventional cab on 110" chassis, you wouldn't have much more than a 4-5' stub to the rear. Might make a nice looking tractor. Good luck with it.
