I have a 14' flatbottom riveted jon boat (4ft. wide floor) w/ a 25hp tiller motor. Nothing fancy. My question is, if I convert my bunk trailer to roller bunks, would it provide enough support for my aluminum boat? I've heard the stories of rollers not providing enough support, but my boat is light and only being supported by the 1 1/2" side of the 2x4 bunks. bunk rollers have rollers that are 3 or 4 inches wide, and i would replace the 2x4s with rollers of the same length. wouldn't this provide at least as much support as the bunks??? the reason i ask is this boat is brand new and i dont wanna screw it up. I'm hoping it lasts me a long time because i will not be able to afford to replace it for many years. I use many different ramps, and on some of the not-so-steep ramps its hard to get the trailer in deep enough to get the boat on and off at low tide. anybody have any experience with roller bunks? What does everybody think? Thanks for your help!!
