When I first got my 2016 Roadrunner (roller) the bow roller / winch extension arm was placed as high as possible on the post, and the bow eye came right under the bow roller.
Mike - I got a 2016 RoadRunner Trailer with bunks. I bought it used, but it hadn't been used much.
The winch was about half way up the post and I adjusted it both up and down and it really didn't seem to sit where I wanted it to. I could get the eye to go just above the roller but then it felt like it was pulling the boat up instead of down onto the trailer and it seemed to bounce around.
I ended up moving it so that the eye is just barely above the roller and the strap is wrapped underneath. The boat was way more stable but the boat should be resting against the roller. Right now the hook is resting against the roller.
My next project is some kind of guide or side bunk. I am also going to put slicks on the front part of my bunks and I am a big fan of anti-skid tape on the fenders so I need to get lots of that.
I know my old trailer was a little undersized and a single axel (neither of these is good) but it was also a lot lower and it was a lot easier to get in and out of the boat. Now I have to make way more effort and I have twice as much anti-skid tape to buy.
I hope to see you in Powell River.
