What does everyone do when there is a water hookup in the campground at your site? Do you still fill your camper water tank or do you just use the hookup and keep your pump off and the tank dry?
I've owned a camper since 2015 and never put a drop of water in the fresh-water tank.
I use the city water hookup, keep the pump off and tank dry. I plan on getting one of those water pressure regulators that go between the spicket and your hose, I see a lot of people using those in the campgrounds.
EDIT: Apparently they are inline water filters.
