I wanted to keep all "mouse-able" food up above the sink, so the dishes had to go below, somehow. In one trailer I used a tilt-out drawer sitting on the floor, which can be picked up and put on the counter (not usually necessary). You have to get it level by a combination of drawer and floor blocks that equal the toe kick height. This "drawer" has been many miles in two different trailers with old axles and has never jumped out of it's place or chipped any china. NOte that the piece that rotates on the toe kick is rounded, as it the back of the toe kick--provides a smooth rotation, yet retains the drawer tightly against the toe kick when it is not tilted.
The other is a standard roll-out drawer under the sink, which has a cut-out for the J-trap.
The rubberized shelf pad provides peace of mind and allows the dishes to be somewhat loose in their cubbies.
