While I was replacing my winch I pushed up on the bow of my boat and I could lift it off the bow stop and the other support (don't know what it's called) that is forward of the rollers on the tongue . The trailer was sitting level, boat was all the way forward, back rollers on transom. I only have 2 sets of rollers, they all look like they are supporting the boat.<br />Is this normal? I'm thinking I need a bow strap to add some down force. This could be part of my bouncing trailer problem. I have moved the axle back 3" and it helped but I still have some bounce on bumps that are not that bumpy. Before I moved the axle I could lift the tongue with one hand. I am not huge 5' 8" 200lb now I can still lift it, takes two hands. <br />I need to weigh the whole boat and trailer, and figure out what tongue weight I need and have now. The weighing will be easy, have a scale near by, but I have to find some thing to weigh the tongue with.<br />The trailer has axle adjustment holes every 3". I find it hard to believe that it was set up 6" off. <br /><br />Steve
