Double Mint: A Dual Purpose, Slammed ’78 GMC Jimmy Showstopper that Seats the Whole Family

Though we love custom vintage trucks, they have one problem: seating is limited for passengers. For Cody McKelvy of Dallas, Texas, GM SUVs have been popular with his family and when he had the opportunity to have Hill’s Hot Rods build this one, he jumped at the opportunity.

When completed, Cody had this to say about the reveal, “My two little girls were freaking out and immediately walked over the seats to sit in the back. I can’t wait to take them to school in it!” This is exactly why builds like this have been such a hit!
