The regulator always goes on the spigot, before anything else is connected. Check with the campground about a sewer line support. Some campgrounds or municipalities require them.
Dutch is correct. Regulator should always be at the campground spigot. It helps to protect not only the plumbing inside the camper, but helps to protect your garden hose too. (although the hose could still burst ... as mine did once)... That sill makes me shrudder thinking about it. If we would have been gone, I would hope a fellow camper would have turned the spigot off for us.
