The off-road mid-size pick-up truck market has been dominated for years by the Tacoma with its TRD off-Road editions but every once in a while GM releases a ZR2 to set a new bar. American Expedition Vehicles and GM performance division teamed up to take the latest iterations of Colorado and Canyon to the next level with AEV specific up-fitted models. Full of options to customize, individualize and build upon a heritage of solid off-the-shelf off-road capability, these trucks were built to maximize expedition and overland capabilities.

While I no longer own the ZR2 Bison, I got a good chance to see it capabilities and spent quite a bit of time upgrading and updating the project along with discovering new things everyday.

Here is "The Build Sheet" final edition for my 2021 Chevrolet Colorado ZR2 Bison 3.6L. - Project Overland Bison
