However, I had my Yamaha Big Bear in the back of my truck.The tie down system held and then broke the upper arm of the system. But the system held long enough to cause just minimal damage to my vehicle. I'm positive that on impact without this system, my atv would have been in my back seat!! Thank you guys so much and I will be purchasing another system for my new truck. It saved my life and my atv. - Aaron Howell, TX
