Good tips, thanks guys and gals. Suppose we will always keep some water in the black tank. I do understand that you keep water in there all the time when you are using it. The reason I asked that question is, its about a 45 min trip to the lake we stay at all summer, so needing to stop for rest breaks at this point in our lives is not a concern, but later on im sure it will be. Being that we are buying this one brand new, we will for sure be babying it for a little while. The campground we stay in has a restroom about 40 feet from our spot, so that's a nice convenience. Its just new, haha. Its going be a queen for at least a little while.
