Single ply TP is the only TP that works well in RVs that have holding tanks. Those holding tanks need to have a chemical additive that breaks down the paper (and everything else). Using anything but single ply in any holding tank is a recipe for a stinky, gooey, messy, disaster.


FYI; Any single ply TP is OK for RVs. You don't need to spend the extra bucks for the special "RV" or "Marine" toilet paper.
