Crawl under the back of the truck with a strong flashlight. The weight rating is probably stamped or embossed onto the frame of the receiver,, back towards where it bolts onto the frame. And the strong beam from a flashlight will make it easier to find the stamp or embossment.
Look for numbers such as 500/5000 WC, 1,000/10,000 WD. That example means 500 pounds max hitch weight and 5,000 pounds max trailer weight with a weight carrying hitch, or 1000 pounds max hitch weight and 10,000 pounds max trailer weight with a weight distributing hitch.
