Ditto on Ford Idaho comment about the TP. With that said, many of us do things that other RVers might not do which is OK especially if it keeps the peace.
It wouldn't hurt to do the TP test just so you can see for yourself the results regardless of using your wife's system.
Great choice for "Living within my means" and camping for one...
