^^^ load er up and go have fun and make some memories!
Keep in mind that you should never overload your tires. A quick stop at the scales can give you ether some peace of mind or flag you to look for better tires.
Hauling truck campers place a 'top heavy' weight in the bed. Some/many users add suspension upgrades/modifications to help with ether or both of 'squat' and 'sway'.
Squat is from the weight of the camper+gear squishing your suspension. While most trucks rear end rides 'high' empty how much squat is to much depends on the user. Personally when oncoming traffic is flashing their lights at me while driving at night I consider that 'to much' and adjust the suspension accordingly.
Sway is the truck/camper moving side to side. It could be in turns, strong breeze or passing trucks. How much is to much depends on the user. Swaybars (or heavier ones) and/or suspension upgrades/updates help with that.
Have fun!
