Driving on the I-5 today, I was passed by a Ford pickup. The sound of the turbo was fairly loud in the exhaust. I looked over, and saw an F-450 medallion on the fender. I've seen F-450 and -550 utility trucks, but I've never seen an F-450 with a normal pickup bed. What would someone need such a heavy-duty pickup for? I didn't see any indication of a fifth-wheel setup. There was a cross-bed toolbox, and not much else. No company name visible.
