Fresh water tank drain

I am new to RVing and can not locate the fresh water tank drain on my new 2015 Cardinal 3875FB. Can anyone point me to the correct spot. Online manuel states open drain valve but doesn't give a clue as to where it is located.

On Cedar Creek the fresh water tank valve is on the tube at the bottom of the tank( under the rv). It's realistically the only place gravity can empty the tank which is necessary to winterize it. Look around, it's there 👍

Our Blue Ridge (made by Cardinal) has a single "blue" tube extending from beneath the underside cover near the rear of the unit. It had a plug in it so I removed it and screwed a elbow into the female coupling and extended a pipe to the rear bumper with a valve on it.

Now I don't have to get under the thing any more to drain the fresh water tank (we do a lot of "dry camping" so we have to take the water with us).
