X3 ...... and on the single-ply from Walmart.
IMO a toilet paper stating it's septic safe doesn't mean it's good for an RV black tank system...., the two systems work differently. A septic system holds the toilet paper for a much longer period of time at the bottom of the tank allowing bacteria to dissolve it over time.
Even using lots of water and a chemical some 2-ply/3-ply toilet paper can still be left behind and bond to the black tank walls like cement (unfortunately seen it happen).
I found using a black tank flush system after each dump helps minimize any size "ply" toilet paper (or solids) from being left behind to "bond".
