I'd have concern they would not dissolve in the tank and could create a plug. Way to find out for sure is to take a personal wipe and put it in a bowl of water. Let it sit for several hours and shake the water. Did it dissolve into fragments (like TP will)? If so, then safe to use. If not, if it stays rigid (like a paper towel), then I'd not want to use it in my RV.
What do others think?
