Those dratted thread-less forest service campground faucets

Some forest service and other public lands primitive campgrounds have a water supply within the campground, but sometimes the faucet does not have a threaded male end, supposedly to prevent campers from hooking up.

To simplify filling your water tank from such a faucet, cut off the end of an old hose about a foot or so from the end. Attach your regular water hose to the good end of the cutoff and slip the cut part over the end of the thread-less faucet.

It’s not perfect and will leak (you can wrap an old rag around it to keep it from squirting) but will get the job done. If the water flow is low and your water tank is large slip a hose clamp on the connection and tighten. This way you can avoid standing there and holding it to keep it from coming off.
