I'm not sure which direction you want to go with this.  It's possible that the dealer is guilty of consumer fraud, and you might be able to return the truck and get your money back, if you overpaid for what you actually got.  If you're just concerned about insurance and registration, I'd think it should not be too hard to get your documents corrected.If you want to pursue this, you should have a local attorney review the paperwork and all of the facts, as soon as possible.
