You can connect a trailer to a truck. But what about attaching the node to a static object, like lets say a tree. With how many off road maps are being made, I think it'd be cool if we had placeable trees or rocks, or just place them within the map editor and when you're near them, you can connect to them and if you're doing some rock crawling, you can help yourself up if need be. There's already the amazing winch attached to the GL83 http://www.beamng.com/resources/gl83.754/ . Having the winch on all trucks or even all vehicles would be great. Plus having the ability to use the environment, with the physics already in place would be a whole new experience.
