I'd skip the 4500 and go for a 6 speed. It's more money and more work, but having had several 4500's and driven a couple of 6 speeds, to me, it's a no brainer. the gap between 3-4 is a pain when hauling even if you spice things up (gov springs, fuel plate)....
that said, I'm "assuming" you are keeping the truck long term
