I'll sometimes need to do a three-point turn where a d90 can clear in one pass. The rear overhang is an issue, but usually I just count on the NAS rear bumper and hitch to protect the truck. You have to watch leaving rocks behind the rear wheel though, cause the body is completely unprotected just aft of the wheel and before the bumper end.
The 110 wheelbase is a big plus sometimes, especially on steep drops and climbs. And it bridges loose stuff nicely, too.
I think 100 is probably the most practical (RR or Disco), but I ain't trading Chammy, so forgetaboutit.
