Absolutely all f250 are single rear wheels while 350s come in single or dual rear wheels. I could see someone taking off the king ranch badges for a lesser trim but again most car people would be able to spot it a mile away.Maybe the plates come back to a F 250 (and same color) so they were disguising it. Preventing it from being discovered as stolen. Although a truck person could tell something was up.
Way back at my first job at a dealership in high school I had to remove the z71 sticker off of a brand new truck. the guy didn’t want the locals to know that he spent extra being he was a township employee I suppose. Loved that job.
