Which method of filling your RV freshwater tank can be used without access to a water spigot and hose?

The gravity fill connection is specifically designed to allow RV owners to fill their freshwater tanks without needing a water spigot and hose. This method typically involves a filler neck placed at the top of the water tank, where water can be poured in directly or where a bucket can be used. This option provides versatility when access to traditional water sources may be limited.

Other choices such as the city water connection and city fill connection require a continuous source of pressurized water, making them unsuitable for scenarios where no water spigot is available. The grey water connection, on the other hand, is used for waste disposal, not for filling freshwater tanks, and would not be appropriate for this situation. Thus, the gravity fill connection stands out as the only option that allows for filling the freshwater tank in the absence of a water spigot and hose.
