I'm no expert. There is a checklist you can use to make sure you have it all together.
Registrar of Imported Vehicles
I brought an airstream over and had to fill out a form at the border. It was not a big deal. They just wanted some tax for it. When I got to the border I needed the bill of sale, and the registration with the owners signature authorizing the sale. If it has never been registered or you don't have the registration papers then there may be other things you need to do.
Make sure the motor is still good! Replacements can be $$$
Good luck.
