Should there be much boat weight on the bow stop? I've always felt like my boat trailer was flexing to much going over hills or road irregularities. I'm thinking of moving the bow stop up some so more weight will be on it. Where its at now its setting down on the roller but if I can lift it about 4" if I pry up with my back. The constant rocking is starting to put a bruise in the fiberglass right above the eye.
