I was reading the previous posts on the weight of the O'Day 25 & trailer and that reminded me of a scary time on the freeway with my 25. I have a dual wheel trailer with brakes and was tooling down the freeway with a borrowed Navigator and it started swaying back and forth when I went over about 50 or so. That much uncontrolled weight moving around so much made me very concerned.Someone mentioned that when they increased the tongue weight, their sway problem went away. Are there other issues I should consider? What causes the sway? Since our sailing season is soon drawing to a close, I want to make sure I can tow it safely home.sPk
