Importation / Tax Questions in the USA

I'm nearing my move back to the USA from Chile. I intend on bringing my Chile bought Series 2A with me. I have the heritage certificate showing that it was originally sold to MOD here in Chile. I have the title in my name. Original engine is installed and purring. Now comes the hard part.

Finding a shipping company. I'll happily take recommendations on that. Many of these firms are global, so I'll take your input no matter where you originated your shipment.

Taxes...this one might get tricky for me. I have a 109 short cab. Some might call it a truck. It has troop carrier seats in the back. The interpretation here might be the different between 2.5% and 25% in taxes. I'd welcome any experience with that. Also, how do they determine the value in which to calculate the tax?

Anything else I should be worried about?
