You did not show your door post tire loading/payload sticker, the one that says not to exceed xxxx. Going by your GVWR of 11,500, and actual truck weight of approx 8,000, you'd have a payload of about 3,500. You will be close to that, with LOADED hitch weight, maybe more?
Your RAWR of 7,230 is the most important number, along with actual tire max rating. If you weigh the truck rear axle, when full of fuel, hitch, you, and all gear, you can subtract the rear axle wt from the 7,230, to see what is left for pin wt of toy hauler.
You will likely be close to max, but the scale will tell.
