Bought mine from BPS 11 years ago and still using it. I can pull up on the trailer and it locks on, but I still attach the winch strap before pulling out. The weight of the boat pulling against the "bolt", as you pull out, over time will bend it. If I have someone in the truck and the ramp is crowded it is nice to pull on the trailer and go. I have had a few compliments over the years.
