you should only have a city water inlet, that screws onto the end of a hose and the FW tank fill inlet, which doesn't thread into a hose.
newer Roos have a winterizing inlet but i don't know much about them, since mine is older and i don't have to winterize living in California.
pics are always more helpful.
