I don't think you will have any problem at all, as long as the boat is loaded so that the trailer takes the bulk of the weight leaving only about 500-1000lbs tongue weight on the hitch (you do have a good hitch rated for this load, right?). Have them shift the boat back if it looks like the truck is squatting too much in the stern. I used to make several trips per year from WA to California with a 3/4 ton Dodge and a three axle trailer with a gross weight of 22,000. You should be under 15,000. The key is getting it balanced correctly so it doesn't affect your steering too much. With the three axles with brakes you won't have any trouble stopping, adjust your trailer brake control by testing it before you get on the highway(if electric brakes). Good luck, take it easy, you'll be fine. Good advice above about checking temp on tires and axle hubs. You'll be stopping often for fuel.
