yea, the %10-%15 rule usually works well. Too much and it really weighs down the back of the truck, to little and it bounces around like all hell behind you and may even pull off the ball(had it happen once to a buddy who hated too much tongue weight) I usually stop when I have around 100lbs though, even on a larger boat. It's easier to handle and still keeps it on the ball real firm. Also, when figuring out your tongue weight don't forget to compensate for fuel loads(dependig on how it affects the CG on the trailer) and also if you have water tanks as well. If you carry 100 gallons of fuel it can make a helluva difference on trailer balance depending on where it sits it the hull. I know it's probably a stupid thing to remind you of but I've seen people balance a trailer empty on fuel and then wonder why it pulls like a dead pig later on with full tanks. :banghead
