Trailer adjustments

[OuluMarine]

Hi guys & girls<br /><br />Is there any rule of thumb for roller width adjustment? Should front rollers be any particular distance apart in relation to the back rollers? I’m putting lots of boats on trailers (at work); they look real good on land but I have no idea if the boat is going on the trailer at the boat ramp easily or not. Also, any suggested reading on trailer adjustment would be appreciated. <br /><br />Thanks for any input.<br /><br /> Ken<br />
