Watch the video above and see what happens when you attempt to exceed your pickup's towing capacity, by a few tons or so. There's really no reason to shout "spoiler alert" here, but it's still fun to watch the GM pickup fire-flame its tires away, only to have the 600-ton mining truck stay completely stationary.
