I recently purchased a 1993 GW Tournament 19 on an alluminum dual axle trailer with surge disc brakes. The trailer is a little oversized (18-24') but in excellent shape. When trailering over bumps like bridge crossings, the whole unit cycles back and forth (bow jumps up and down too). It feels like the brakes are grabbing and letting go in a cycle. I have tried tieing down the bow to the trailer, and that has helped a little bit, but it still goes ina cycle onthe worst bumps. I am towing with a suburban 1/2 ton and tongue weight is around 275#...only reference that I have seen is that tongue weight should be about 5-7% of trailer and boat. I was told that the total weight of the package should be around 3,000 # is that right? I usually keep the fuel tank full. any insight would be appreciated
thanks
