Cool truck. If you could get it you would be way ahead from what alot of us start out with.
Here in SC property ownership is public record. Most, but not all, counties here have this info on the web. You might try searching for your county tax assesors office or a parcel map online. Most counties here are also searchable by address. If you can find out who owns the property the truck is sitting on, that should give you a lead on who owns the truck. Unfortunately vehicle ownership isn't as transparent here. This is just an idea. of course, your results may vary.
