I bought and imported mine a long time ago and the process has changed. Essentially, now you have to use a customs broker to access the electronic customs system and get a notification number (AES) before you can get the export inspection on the US side done.
Self-importing a vehicle has been made more complicated than giving CBP 72h notice, a copy of the title and then showing up.
There are companies that offer this service and it may be a good idea to talk to them. The border is less and less a place where individuals are welcome to do personal business...
If you absolutely want to treat yourself to the whole process, perhaps start here:
Learn about importing non-regulated vehicles; includes vehicles not regulated by the Motor Vehicle Safety Act, importing older vehicles, importing utility-terrain vehicles and importing power assisted bicycles

As long as the vehicle is at least 15 years old, you’ll be able to import it into Canada without worrying about the Registrar of Imported Vehicles (RIV) or Transport Canada, which regulates the importation of vehicles into Canada. If the vehicle is more than 25 years old and in its original...

As for the EUC, this has no relevance in Canada. The EUC is a SELLER'S document and usually needed by commercial resellers of military hardware to demonstrate to Uncle Sam that they do not sell stuff to unfriendly people or nations. Canada, last I checked, was a US ally.
Also, make darn sure that your Province will issue a registration for the Deuce before you import. A smooth import is no guarantee for registration. Also, if you intend to drive the truck, you need to sort out insurance and temporary plates. Insurance is usually ok, but plates can be quite the challenge....
In the US, the state may not want to give you a temporary permit because you are not a resident or because the vehicle moves out of state. They will suggest that you need to get a trip permit from the province you intend to register the vehicle. Your province may tell you (as mine did), that the vehicle needs to be physically present in the province to receive a trip permit. See the challenge?
So - check online for the State you are buying from. I bought a classic semi tractor from VT a couple years ago and that state issued me a trip permit, no issues. 11 bucks, I think.
I also say that, for this import, I had one of the car import companies handle all the paperwork. All I needed to do was be at the border on a certain day at a certain time. I could not be arsed today to jump through all the hoops, figure out every detail of this process and get the paperwork in order all by myself. For me, paying someone in the know a few bucks hurts way less than being stuck at the border for a day, trying to sort things out! Your mileage may vary.
