Has anyone added a bogie wheel to help maintain a little more constant tension

in the front of the rhino drive? We've got ours completed and I got a little nervous in the service when I only saw a turnbuckle tensioner. I'm just an old tanker and frankly don't care for having track casualties in the middle of competition. I'm sure I'm going over the top but...if it can crap out it will for our team. haha
