This is really for the OP, but I checked the Ford website and they still offer a 9900# F350. So you can get the camper package, getting the max springs, but the door sticker will say 9900#. Our fleet manager used to get our guys these trucks, so they could take their trucks home. Most of us only look at RV's, but Ford and Chevy (at least used to) make these trucks for the only reason that matters. Customers buy them.
So for the OP, I think the 10k or 3/4 ton trucks also pay less on the ferries and over the bridges off the island. Of course I am a cheap ba**ard.
