Was hooking my Gambler up on the hitch today to get some gas for my weekend fishing trip and noticed when I put the boat on the ball moved a little bit. Having an inquiring mind, I look down and noticed there was no washer or nut. First time this has ever happened and hopefully the last. I periodically check, but had not done it in a while. All of the times I checked over the years it was never in a bit loose. The moral of the story is to check your towing package.....................
