I'm planning a total replacement of the deck in my bowrider this off season. I'll be blocking up the boat & taking the trailer out from under it. I noticed the bunk on the one side is rotting out toward the rear. I want to replace & got to thinking, could I/ should I replace with rollers. What would the best choice be? I saw a guy loading this past Sunday & it looked pretty easy with the rollers. How hard to convert to rollers? Just asking......
