I had already attempted my first try at emptying the RV tanks on my way home with great trepidation. I made sure I had full hook-ups at the last campground I stayed at, as I had no where to dump them when I got home. I figured it would be easier to do at my campsite than at a dump station where there might be a line of other campers waiting for me to get done, and critiquing my every move (and mistake).
I did ok, but was glad I could take my time. Even so, I had a few surprises. I'm a reasonably educated person, and somewhere in the back of my mind I'm sure I knew that if you squeezed together a hose that was made like an accordion, it would reduce the volume of the interior space, therefore causing the contents of that space to have nowhere to go but out. After a few splatters that caused me to have to change my clothes, I got the deed done, and firmly committed to memory the order in which you want to disconnect each end of the hose from the RV and dump drain, and why it's good to thoroughly let it drain before compressing the hose it to put it away.
I now had a different problem with the dump situation. I had been using the RV toilet for a week, and it was getting full. I started filling jugs of water in town and trying to use the bathroom in the house. The amount of water needed to pour down the commode to properly flush it was getting to be more than I could keep up with. I set my mind to solving the problem of how I could dump my RV tank with no dump station.
