we just bought a new trailer and don't take delivery until next spring. It has 2 dump connections for grey water and 1 for black. Does anyone have an idea on which would be best way to hook these up when parked for a few months. Do not want hookup and disconnect each time we want to drain tanks. Also we will be travelling so the solution must be portable. When we are at our summer location at the golf course I will use ABS pipe and make a permanent drain but when moving around it could be an adventure. Thank you for any input.
