In the Sabre 291 BHTS, there is a storage area under the fridge, which is what used to be used for the exterior slide-out tv option. Now, we hadn't opted for the pull-out tv, but thought we would still have the exterior access hatch. When our camper arrived my wife was pleased to find that the area was utilized as an interior storage compartment.
But then she asked me if i could do something about that hinged door. I had built a similar contraption in the kitchen in our house for the trash can, where the door is attached to the drawer, so it all functions like a one piece drawer, but looks like just another cabinet door when closed.
I simply removed the cabinet hinges and attached the door directly to the hidden sliding drawer. I had to tweak the drawer slides a little for square, since now that the door is part of the sliding mechanism it exposed the fact that the hidden drawer was not perfectly square and plum in the hole
