While we haven’t used this gadget a lot, when we have, it has saved us from grief or having to pay to stay somewhere when we hadn’t planned on it. So it’s a good gadget to have in your RV arsenal, particularly when boondocking or camping at a primitive campground.
This is design for filling your RV freshwater tank.
This is for filling your freshwater tank though, it is not designed for long-term connections or pressurized situations like running it as a city water connection. It will work for any motorhome, travel trailer, van, or fifth-wheel that fills with a standard RV freshwater hose.
Bonus tip: For particularly difficult faucets, slip a worm clamp on (see photo), which are very cheap at any hardware store, and tighten a little for a better grip.
