Also remember you don't need to hook up the water and sewer hose all the time you pull into a site. Just fill the fresh water tank and use it till you need to refill it. And drain the gray and black tanks as they fill up. This will save you time when you want to take off for the day sight seeing. The electric you may want to hook up each night if the site has electricity, will let you use the microwave and A/C if you have it.
When you hook up the sewer hose drain a little gray water first to make sure connections are not leaking, then shut the gray, and drain the black tank then the gray tank to flush out the sewer have. Have fun
