Duties on your rig are classified as a MPV(multi purpose vehicle) therefore, they are scheduled at 2.5% of the purchase price. Due at crossing. Here's a tip: Plan your route home from pickup. Determine the border crossing and call them ahead of time. There are import specialists that can answer your questions. Look up the U.S.Customs site. It will give you phone numbers to each specific crossing. So call ahead of time that way your squared away when you arrive. Easier for you and especailly for them. They hold the power to stop your entry. I found them to be very helpful and friendly,But thorough. which is fine by me that's what we're paying them for. I just imported one a week ago. Had to use an RI because mine was a 83BJ42. Feel free to contact me if you have any more questions.Good luck
