All that talk about how inconvienent it is, I don't understand.
I spent 10 days in ours, by myself. At the end of 10 days I just ran out of water and had just filled the gray tank. It mustn't have been empty when I started. Cook meals, took a (short) shower every day etc. if you get one with big tanks, a week between dumping/filling w water is easy. Not like you don't run out of water and dump the poo in any other rv.
If you're unhooked and need water Ina remote area, you can haul water to it cheap and easy in your PICKUP Truck. Overall they're pretty handy.
If it didn't need the benches, table and bunk, I'd figure out how to get a couch or chair in it instead. That's the only sucky feature is no where real comfortable to sit.
