Tracking down the 28W hot water bypass

Ok, this is getting a tad frustrating...

My 2011 International manual states that the 28W hot water bypass is behind a panel in the lower section of the hallway wardrobe; yet when when I remove that panel, I see 8-12 different pipe runs, but not a single pipe with any identifiable valve.

Yet the manual also shows a single switch on the rear of the hot water tank mechanism for the 30 -- this switch I can see in the cubby hole beneath the front L-Lounge.

Can anyone with a 2011-2015 International series 28W provide guidance/feedback as to where they've located their bypasses (photos would help!) I _really_ don't want to spend another $90 having a third party winterize when I ought be doing it myself.

Cheers thanks,

We have a 30' and ours is under the dinette seat nearest the television. Thru a small hole in the plywood you should see a yellow valve, if so that is the one, turn it closed and you are done with HW bypass.

Ours is a single yellow-handled valve as well located on a water line just before and going into the water heater. Accessed through a small cabinet door inside the Airstream.
