I hook the garden hose up to the city water inlet at home and fill the water heater and purge the air from all the lines. When I arrive at the CG I swing through the dump station or wherever the potable water spigot is and fill the potable water holding tank on the trailer. Makes for a lot less dinky donkin around at the campground.
