Skip the RV emery cloth (uh...I mean toilet paper) and use Angel Soft double-ply TP or the Walmart Good Value brand single ply TP.
Both work great in my RV.
But don't use 1/2 a roll for each wipe of the booty...
And, don't forget to flush paper down each time with plenty of water.
We actually did a test of TP at a rally a couple of years ago where we put several brands of TP along with the RV brands each separately in a mason jar and let them sit for five minutes in plain water, then shook them up.
The Angel Soft was the only brand that completely disintegrated after 5 minutes in the water while the rest all still held their shape mostly.
The Walmart brand I bought as the Angel Soft was not available at that particular Walmart (T or C, NM) and I bought what seemed to be a 1000 roll package that lasted several months (still have some in there) in my RV while full-timing and flushed out without any issues.
