In our A liner, we removed all cushions and the table. In it's place, we put a good mattress for a futon and leave the bed made up all the time. Handy husband built in cupboards with sliding doors at the front and we modified the dinette seats to 2/3 size to allow the cupboard. We use lap trays to eat, if we eat indoors. He also made a counter on legs which sits over the sink so I have more counter space. As you said, you didn't wish to modify your camper but we did. We've been on a 5 week trip to Alaska and a 3 week trip to the West Coast. No complaints. You learn to do with much less and it works for just the two of us.
