Trailer dealers that ship??

IMHO - The contact area where the roller actually support the boat are very small compared to the contact area on a bunk. Bunks have more friction to overcome when loading and unloading but support the boat better. Rolers are kinda like standing on a bed of nails. I'd worry about damaging the boat while towing. Bunks flex some, seems to me they would be more forgiving. Properly adjusted bunks shouldn't be that hard to load and unload. Plus compare the cost to replacing 2 bunks to how ever many rollers on a roller trailer.
