Travis Hunter's a Colorado Buffalo, but he now drives a RAM ... and TMZ Sports has learned it features some crazy modifications!!!
The college football star landed the truck as a surprise present from his fiancée, Leanna, for his 21st birthday earlier this month ... and Dreamworks Motorsports honcho Adam Wolfe tells us it's a "1-of-1" ride.
Wolfe says he and his team spent about a week tricking it out for Deion Sanders' two-way player .
