Folks make too much of this.
Not sure what else a scale will tell you. Your truck has 3000-3500 on the rear axle before camper. Camper adds 3600lbs per specs. Your wheels are rated around 3500 generally for Oe wheels. Tires are what they are but 3500-4000lb tires are the norm. Axle good for 10k
As long as you’re good with 3500-4000lbs of pin weight, let er rip.
Might be a bit less with the toys loaded.
I’d do it. You’ll need more springs, or bags and some good tars and Oe wheels slightly overloaded
Yes you’ll be over rated payload, but you should already know that. Beyond that , if you don’t understand vehicles, it’s hard to explain.
