Stinger TerraFrame Designs offer more opportunities for customization than the typical OTR (over-the-road) truck or custom chassis manufacturer. That’s because most of the limitations that apply to building a production OTR truck simply do not apply when it comes to our TerraFrame designs that are built from the ground up. Our designs are only built for the heavy duty, off-road custom market. Each unit is designed specifically for its unique function, use and environment. Using our decades of experience building and operating off-road equipment we strive to seamlessly blend the use of new technologies and products with as many common, time tested and proven components and designs.
