when I did it it asked for proof of purchase. I included my title that showed the purchase date as well as the sales agreement. It may be different if you were not the first purchaser of the truck.Supporting documentation required to complete your claim may include:
Current vehicle registration (if applicable);
Your driver’s license or other government-issued identification;
Dates you owned or leased the Eligible Vehicle; and
Sufficient proof of current or former ownership or lease (as applicable).
