I daily drive my F450 CCLB DRW, putting far more miles per year than most of you. I have no problems with parking or drive thru's. About the only thing I stay away from are parking garages due to height issues. I DO have one advantage over most, the wide track front axle. This truck turns sharper than any truck I've ever owned. It would be very hard for me to go back to a SRW CCLB truck now that I've experienced the ease of maneuvering this feature offers.
As far as the long bed goes...as posted earlier, real trucks that do real work have long beds. If you cant haul 8' plywood/drywall/lumber in the bed, the truck is useless to me. Longer lumber goes on the rack. I'd take a 10'pickup bed if they offered it.
