I have a 10K mounted with no problems. I did have the winch fail over the summer but ENGO's customer service was top notch and sent me a replacement part double quick. They even gave me a number to call them on a Saturday for instructions on how to replace the part. He stayed on the phone with me the entire time while I fixed it. Pretty cool.
