I think the basics have been listed. Put a coup;e oz. of bleach in your fresh water tank, fill it up and run some through all your stuff from the sinks to the toilet. Not needed to go through your hot water tank. rinse and then put in a few gallons of fresh water . No need to fill tank but good to have some water for potty stops while traveling. If it is hard winter at home we just carry a couple of gallons in jugs till we get south. One other thing rain gear, a hat a set of those lights that go on the hat and a good flashlight.
