I agree with other comments, just adding my 3 cents. once you get it, stay at home at least a couple nights if you can. If not go to a near by place and set up. this will allow you to familiar yourself with the workings of the unit. Learn how to be conservative on water and electricity. Even going to an RV park and set up but not using electric and water will be good for you to understand the workings and capacities. You will be in a place to flush and fill if needed earlier than what you may expect. There will be others in the park that would be glad to help understand things. Don't go and buy the farm before you go, add things that you want as you go and be careful about buying every gimmick and gadget there is. The list goes on and on. Good Luck & Be Safe ! ! !
