I also thought I would be clever and cut a hole next to the steps into a storage compartment beside it. No problem, take out carpet, cut through wood, aluminum, and plastic casing. However, after I got underneath the rig, I saw that the stairs were housed in a thick steel frame casing, with an opening that only a kitten could slide through and great difficulty in accessing it anyway. It sure depends on your rig setup. If I hadn't had a slide mechanism under my bed, I would have tried to cut an access door through the bed bottom and then would have cut a door in the floor to the basement. How about underneath the dinette seats? I can't do this because of some huge metal brackets that hold seat belts, but your rig might be different. I have three cats, 1 litter box, and I scoop it twice a day.
