Different answers depending on the unit. If you have a gravity fill type where you can stick the hose in the hole and fill you generally will have an air vent right there at the fill point. When it is getting close to full it will start spitting water at you. At that point slow down your fill rate to get in as much as possible without getting soaked by the overflow. If you have a hose end connection where you screw the hose on you will generally have overflow tubes/hoses coming out under the trailer somewhere. When the tank is full, water will start coming out of these. If you fill it and then start driving you will also see water coming out of these quite often.
