Int'l 23D HW tank bypass valve location?

[DreamsInSlvr]

Hello Experienced AS Owners:
I am getting ready to winterized and am asking for help in locating the hot water tank by pass valve. I have found the white and red low point drains in the rear storage compartment, but am wondering WHERE the by pass valve is for the hot water tank. The AS manual indicates it is in this compartment as well. Confused!

We had an older 23D at one time. As I recall, the by-pass valve was under the mattress.

Thanks or the hint. Upon closer examination, there are actually TWO access holes under the mattress! The one closer to the footboard allows access to the hot water heater bypass valve. The second photo shows the yellow valve and a sticker showing the correct position for winterization mode.

Thanks again for clearing up this mystery.
