I went out to the rig today and started looking around. I believe I have developed a plan.
Since this dinette is a booth placing the crates under the dinette is a non-starter.
I am going to use the over cab bunk area. I took some measurements and I plan to take the mattress pad off that area, bag it and put it in a safe place for storage. I will then build a frame that will elevate a platform about 2 inches above the cab platform. This frame will get secured to the over cab framing so it is semi-permanent. I will then get some drawer glides and build three crate platforms and secure them to the elevated platform. I will then secure the crates to there own sliding platform which will allow the crates to be pulled towards the rear for cat loading, unloading and crate cleaning. They will be locked forward for travelling.
I plan to build it so the entire setup can be removed should our grandson want to take a trip with us and use his "bunkle" bed at night.
Unless a better solution presents itself I will probably start building the setup in about 2 weeks.
