Bill, I just went and checked my 2012 HT 26.5 RLS, both the door-side storage and the front storage on the door side and found nothing like you described. I did find two low point drains, as indicated on the outside of the access door and on the front storage I found the control panel for the bedroom wardrobe slide by Schwintec but nothing like you described. Maybe you could call Jayco and ask them what is there. Maybe a floor plan on the web site would help you. Or, talk to your dealer, they might know.
