Another piece of the "Just how small is that boy?" puzzle may just dropped into place. I am racking my brain trying to identify the make and model of that truck. I am not 100% on this but I think it's an early 00's Chevy Silverado, the squared fender flair, round gas tank door, small badge right behind the edge of the door, and the styling crease 1/3rd of the way up the body are a pretty close match. Size wise it looks more like a Ford Ranger or Chevy S10 but the styling isn't the same and their gas tank doors are square. And the older Toyota Tacoma and Tundra and Nissan Frontier have rounded fender flairs. It could be a 20 year old F150 but I don't think so.
It's also riding on OEM wheels and tires and it doesn't appear to have been lifted or lowered so it's at stock ride height.
