2006 Venture VRT-4100. I was going to add keel rollers to front and rear supports. Any idea on the spacing between side rollers so it will rest nicely on the keel rollers? I'd rather not be going up and down a ramp playing with it if I don't have to.
Big
The boat's weight should be totally on the keel rollers and the side rollers should only stabilize the boat laterally. You'll pretty much have to put the boat on the trailer to set it up properly.
Good luck.
