I'll use the water!
Confucius say "Happy wife -- happy life" ...
You ain't washing, you ain't riding! I'll use the water Thank you!
Confucius also say:
"He who fly upside down have crackup!"
Wash it!
And who'll be the first here to have an on-board bidet?

When I was driving truck, I converted my 8ft storage box on the tractor to a full sleeper with shower, toilet, sink, refer, microwave, etc. I carried 75gal of water and filling was rarely a problem since most truck stops have water spigets on the fuel islands. Dumping the gray wasn't a problem-just let it loose at night in the truck stop. The black I dumped once a week. Usually at a rest stop that had free dumps, or at Flying J. Once you had all facilities on board, all the tension of driving just went away. Good Luck, TomC
