Anyone else have this problem? I've got a dual axle trailer, and I resorted to putting sliders on it. The two center bunks, five each from back to front. It helped, but just barely. Doesn't matter if I completely submerge the trailer to soak the bunks, I still have to dead lift the nose of the boat and push it back as far as I can(and it ain't easy) before gunning the motor to barely get it to float off. Any suggestions?
