I bought a storage tub from home depot and just put it in there. Keep a ton of stuff in it. Doesnt fit with the lid on but does a great job of keeping stuff i dont use often out of the way…mooring ropes, fenders, xtra trolling motor prop, jumper cables, oil, gas treatment, basic tools. It was just too big a space not to use. Had a triton with those trays you are talking about. I took them out because they were too shallow to be of much use to me and had to constantly take them out to bet to batteries. Caracals space is huge and interferes with absolutely nothing.
