I am still working on tweaking the inside. I did not want an industrial look nor did I have the desire to carry what looked like furniture. I do not need built in cabinets etc. I want to camp, sit by the fire, enjoy the outdoors but with less work than pitching a tent involves. I have also learned that in inclement weather, I want to stay dry. I put a twin mattress with a 3 inch memory foam topper inside, on a twin wooden platform that is slightly elevated by bricks wrapped in towels so as not to be abrasive on the base of the mattress. Under the wood frame I have some room for storage such as for my single burner butane stove, Ziplock bags, etc. I still may work out a pull out tray system of some kind.
