Shes not the newest, or the latest, but she's awesome. The furnace works great (but will kill the battery in one night), the slideout makes plenty of room and she tows like a dream. 20A electrical connection allows for power inside. We replaced the front storage when it cracked with an expanded mesh basket for hauling firewood, kids bikes, the generator, or whatever else you can think of. Both ends pop out into king sized beds with new Coleman brand mattresses. It does have a fresh water tank but due to the weight we do not really ever use it. I clean it every spring to keep it from getting stanky but its not a feature we use for ourselves. It does not have any kind of grey water tank, the outlet just exits the unit so you have to connect it to a hose or put a 5 gallon bucket under it to catch water from the sink, to be disposed of later. There is no water heater for it presently, and we never use the fresh water tank. Like I said, she's not fancy, but she's a roomy, warm place to sleep and pulls very well. We currently pull it with our Toyota Sienna minivan.
