What can a Toyota 4Runner (4.0 V6) ('11-24) actually tow?

The rating is the easy half of the answer. A trailer never weighs its brochure dry weight — water is 8.34 lb a gallon, propane and batteries ride along, and so does your gear — and hundreds of models changed their published weights mid-run, so the model year decides as much as the model. Judged that way, with a 10% margin and 2 people aboard: 723 of 5150 campers fit a Toyota 4Runner (4.0 V6), and 7 more fit if you buy the right years.
The number that quietly binds is payload — 1,700 lb (SR5 2WD - GVWR 6,100 lb minus curb 4,400 lb, per Toyota's own definition of payload. 4WD trims run about 1,550 lb (GVWR 6,300, curb 4,750).): tongue weight lands on the rear axle with your passengers and the hitch, so a vehicle often runs out of payload well before it runs out of rating.
1603 fifth wheels are excluded outright: a fifth-wheel hitch mounts in a pickup bed, and the Toyota 4Runner (4.0 V6) has none — at any rating.
Loaded estimate: dry weight + full fresh tank + propane, battery and gear for 2. Headroom is against the rating less 10%.
FIT — IF YOU BUY THE RIGHT YEARS
These changed their published weights mid-run: some model years clear a Toyota 4Runner (4.0 V6), others don't. A listing site treats them as one trailer. They aren't.
That depends on what you care about — bunks for the kids, build quality, budget, weight you'd rather not tow. Set your priorities as sliders and watch all of these re-rank around them, live, with your vehicle already filled in. Nothing gets hidden.
