Sewer Solution

Since I usually camp at a state park just 25 miles away and am retired, I go midweek when there aren't many camping and dumping. I don't see much problem with dumping and holding anyone up when using the SS. I could use a second back flow preventer at the pipe as suggested. Plus, if there is a line waiting to dump, I would just go home and dump the camper there. Since I am not only a widow, but have also had a knee replacement, using the drain as it came on the 2004 Roadtrek would be extremely difficult and I can't afford an installed macerator. The SS would be a simple and inexpensive "solution" to my continued camping. I don't think I can continue camping with the Roadtrek as it is now.
