T660 wheel base

[schmud0811]

Need some user input on Spec'ing out a new truck.

Currently have the wheelbase set at 265 but can go longer. Truck in question is a 2013 kenworth t660. I need the wheelbase long enough to haul a 6' front overhang. Anyone out their running a 660 pulling long loads with a front overhang?

I'm trying to keep the truck as short as possible but want to be able to put a 14" deep closet rack on the back also.
Sleeper will be a standard 72" aero cab grass burner exhaust

My neighbor has a 2012 Coronado with the 70" bunk and has a 280" wheelbase. He pulls long beams often and has not had any problems. His old 379 had a 300" and with the setback axle, the Coronado has more room between the bunk and trailer.
