The payload and tow rating numbers are derived and probably overstated. Ignore them.
The GVWR is a real number, and is probably your limiter as to how much trailer you can tow without exceeding any of Toy's weight limits. So here's the drill:
Load the Toy with family, tools, and anything else that will be in it when towing. Go to a truckstop that has a certified automated truck scale, such as a CAT scale or J scale. Fill up with gas, then weigh the wet and loaded pickup. Subtract the weight of the wet and loaded pickup from the GVWR of the pickup and the answer is your real-world payload available for trailer hitch weight.
Divide that available payload by 0.15, and the answer is the maximum GVWR of any TT you want to consider.
Your wet and loaded pickup weighs 6,400 pounds. That leaves 800 pounds for hitch weight. 800 divided by 0.15 = 5,333. So don't consider any TT with a GVWR over 5,333 pounds.
Your wet and loaded pickup weighs 6,300 pounds. That leaves 900 pounds for hitch weight. 900 divided by 0.15 = 6,000. So don't consider any TT with a GVWR over 6,000 pounds.
There are some small, lightweight bunkhouse TTs with GVWR less than 6,000 pounds. For example, here's one:
< Heartland Lightweight Trailers | Heartland RVs
That one doesn't have a slide, but if you can keep the wet and loaded weight of your Toy down to less than 6,300 pounds, then you can tow that one without being overloaded.
