Propane hose with plug-in grommet/coupling pin for quick coupling
After I got my new motorhome, a few improvements were made. One of them is a connection for a gas hose, so that I can easily use the gas stove to cook outside without having to haul along a gas bottle or take one out. It's less than 30 euros and 300 cm long, so it's a perfect addition. Amazon* ⇒ h
