Thanks for the info. It does have a grey water tank, the floor plan is couch on both sides that turn into one big bed, over cab fold down for my 2 year old. The heater is a interesting one in that it is not a forced air furnace but a wall mounted heater hooked to a thermostat. THe bathroom does have the fold down toilet which I like because it gives more room for when you are showering. At some point I would really like to put a outdoor shower but that is way off in the future. Now we have to replace the cushions and fabric, rip out the carpet and put down some kind of flooring, take out the blinds and make curtains, and do a general deep clean. Really looking forward to making it ours. Thanks again.
