NO, NO, NO........
It's an RV and you must use RV specific toilet paper.
RV'n is different and therefore all logic must go out the window.
Sorry......
RV has huge dump lines from toilet to tank. Tank has a large drain line going out
Stuff from toilet only has to fall a few feet into tank......stuff in home has to travel many feet to get to septic tank/sewer line.
Water carries the stuff along....plus gravity.
If you use TP fill toilet bowl full prior to flushing.
There are several things that should not go into an RV toilet and into tank......cells phones, kids toys, wipes etc. but TP isn't one.
Use what your bottom likes.......then flush it with a full bowl of water.
Dump black tank when it is full so that the liquid can carry the stuff out the big ole drain line.
