Not sure I need this wheel mount as my trailer is small and I put it under the wheels but figured it wouldn't hurt to be extra careful. I'm glad I bought it! It's small but strong and sturdy! This gives me the added peace of mind that my front wheel is docked and won't move an inch! It's small but fits perfectly and I love the rope attached to it. You might think this isn't necessary, but it certainly helps with the removal. It's the little things in life that put a smile on your face!
