There is no doubt that bunk trailers better support a boat!
But they have come a long way with roller trailers over the years!!
Gone are the trouble some keel rollers! The roller shafts are now flat on 2 sides, allowing the rust and dirt to just roll out when you use the trailer.
Older trailers used round shafts which trapped dirt and rust to the point that the rollers could not move anymore.
And most now have a good amount of rollers to support boats better.
It just depends on your needs, I guess we have bigger tides and steeper ramps here, that make a roller more necessary?
Eaither way I love my roller, and it has been the best thing I have ever bought to make boating easier!!
