Mike,
If your state does bonded titles, it will have state rules/form/procedures (probably described on-line).
You might need ID code/numbers - Engine Serial Number and/or Vehicle Serial Number.
You would need a notarized bill of sale, and most likely a title/registration.
You need a vehicle insurance policy in that state.
I had to get a bonded title in NC for my Suburban, even though it had been registered in NY since 1981 (first registered by me in VA in 1971). Luckily, my NY title was based on the Vehicle Serial Number (the engine had that serial number ground off it, many years ago, pre-1971).
I needed a bonded title because I had taken my ID plate off the Suburban for restoration cleaning/painting. Therefore, the NC DMV had no satisfactory proof that the ID plate came off my my Suburban. They told me that new attachment screws/rivets and/or a new looking plate would raise their suspicions.
They told me that new-looking attachment screws cause them to require a bonded title (or, at their choice, they could simply refuse NC title/registration).
In NC (a few months ago), they gave me two new NC ID tags, in place of an ID plate. They installed one new tag in/near the original plate's location (and, one new tag in a secret location) - they took pictures of the tags on the truck, and they took several photos of the truck. When/if a NC police officer stops my Suburban, they can now run/check my new 2017 NC license plate (another story here - I legally have/display a 1954 NC original truck plate on the Suburban). When they run my new NC plate from a patrol car, several photos of the Suburban are displayed to the officer (two photos are of the new NC ID tags).
I will also have to get bonded titles for the two trucks that I am restoring - both had ID plates removed by me during restoration - both were registered in NY by me (luckily).
