Interesting reply Otto. Good advice but you left out a few key details. The 350lbs sounds about right for the tongue weight. If you don't have a tongue scale get a few buddies and use this method. Measure the height of the top of your truck bed to the ground, then have two guys (about 350 pounds) stand on the bumper by the hitch.. remeasure the bed height and note the change. First I'd make sure the boat is on the trailer in the right place. Bunks should be right even with the stern and rollers about 2" in. Then I would move the axles back 12" to start, hook the boat to the truck and check the bed height to the weighted height, slide the axles forward or back to get the right bed height. Once your close to the weighted bed height, lock down the axles. Next step.. and the most important step. Measure from the ground to the underside of the trailer frame BETWEEN the axles. Take that measurement and go to the tongue of the trailer. The underside of the tongue(which should be on the same level as the frame rails) needs to be the same height as the underside of the frame rails between the axles. Undo the ball coupler and jack or lower the tongue until these two numbers are the same. If it's higher or lower I'll need to get the same "raise or drop" to match the trailer. Drawtite and Reese make a few different sizes of inserts that will fit into your reciever. The tongue weight is important but tongue height will make or break you. The right tongue height will make sure the trailer tracks right and the load is equal on all four tires.
