So, behind the base cabinet door, I built 3 drawers with ball bearing RV full extension slides, 16" deep except the top one which could be 10" deep due to the waste pipe. These drawers were quite a chore as I had to relocate waste and water supply pipes. I also had to had to install plywood on each side of the drawers to attach the slides to. Not easy because nothing much in a trailer is square, plumb, level or even from side to side. Arghh, I've forgotten the countless hours I spent setting the sides up! The drawer fronts are slolid oak with recessed Hafele finger pulls to clear the cabinet door.
In this photo, you can also see a water pressure gauge I installed. I put it there so it's readily visible to check.
