When I bought my Skipper last year in Campbell river the ride down island was a little scary.The trailer wasn't set up right for the boat,not enough tongue weight.Every time I went over a bump it felt like it was trying to pull up on the hitch. I ended up sliding the axle back 7" and it solved the problem,easy to do,just had to replace one brake line.The boats weight is right on the borderline of getting a single or dual axle,my single axle seems fine so far. Tuff trailer makes a nice single over 5000 lb. capacity.
