I have one for my 21 ft sea ray no issues. Mine is a 2004 I've owned for three years. Boat sat and wasn't cared for so brakes were frozen, I replaced brakes and tires, fixed one tailight.
Do do I think it the worlds best trailer? No, but been more than adequate, and tows really nice, tracks well no sway at all. Farthest I've towed is 350 miles one way trip, generally much shorter.
