Not a lot of information on this incredible mod but as far as I can tell it’s a Hummer H2T (the pickup truck model of the H2) modified with a cool black/green paint job and tank treads. These tracked belts actually work, meaning you could scale some serious mountains with this bad boy. Unfortunately, there’s no word on top speed, meaning this Hummer could be slower than Ryan on a skateboard.
Those tracks look like the Mattrack Litefoot conversion set. It’s just a bolt-on component, if you can change a tire, you can install those. The only custom touch is the matching paint scheme.
