Hey Guys<br />I have a trailer that has bunks and rollers and it all needs to be replaced.I have found a composite bunk board which I plan on using.My question is should I replace the rollers or just add a few more bunk boards.The boat is 22ft and weights about 3800lbs.I have never launched the boat as I purchased it late last year.It is a large boat and want to launch it as easy as possible.Any advice is helpful,Thanks
