The Magnitude has the fresh water tank drain under the bed like the XG32. It may have been left over if they winterized the coach or during manufacturing.
The drain exit is under the coach. I bought some PVC and glued it off the drain and added another shut off valve so I don't need to take the ned apart to drain the fresh water tank.
There was another post where they installed an electric valve in place of the manual shut off so they just flip a switch to drain the tank.
