GO to Lowes or Home Depot, and check out the single drawer Fisher Paykel Dishdrawer. That is what is in my Bounder, it fit just below the sink, and I only had to make a few modifications. It is the standard 24" wide, but only about 19" tall. I put a shelf on top of the dishdrawer, then had a opening about 24" X 9" to cover. My right hand door for my sink undercounter area fit just right.
Sorry, no pictures, and it is in storage right now.
You can "Lock" this brand dishwasher, then shut off power to it, and it will not slide open while driving.
It is a option in Bluebird motorhomes, that is where I got the idea.
