As a person that deals a lot with boats, that thing weighs over 4500. But even if it does somehow only weigh 4500 I still wouldn't do that to your truck. Since you're only doing it one time, I would hitch a ride or flight then rent a Uhaul pickup for the trip. The pickups start at $19 / day plus mileage. Since your truck is brand new, I would not do that to it. The sheer size of that boat alone makes me nervous for you with any kind of wind.
Long story short I personally would not do it. But hey, it's your $35,000 investment so do what you want.
