You have zero to worry about.
Your truck is a little under 3klbs on the rear axle, empty, so the camper is sitting at about 2600-2800 lbs now.
With all your stuff in it ready to roll, worst case it’s maybe 3800lbs.
Unless you collect a lot of rocks.....dont laugh, some do, lol lol.
Load up some stuff. Make some temporary spring wedges and see if that’s enough support. It may be. If it is, that and a sway bar and you’ll be golden.
Adding the boat, you might think about adding something else non elaborate. Simple airbags, bolt on helper spring or Timbrens. IF you need them.
You won’t get an appreciable amount of weight on the front axle. Not worth the pain of trying. Best case only a few hundred lbs will be on the front axle since it’s a short Bed truck.
