I've been using Scott's 1000 single ply in the trailer for (I'm guessing here) the last 10 or 12 years. I always use plenty of water and have not had an issue with odor or blockage/valve closure problems using this TP. It's strong enough to not break apart while wiping <YECHT> but does break apart in the tank. It still comes out the sewer port (viewed with the clear hose adapter) in clumps, but the other end of the sewer hose just shows "chocolate milk consistency" effluent.
I have no doubt, as Danny said, others will disagree and I'd suppose that's one of many reasons even WalMart has 50+ brands and types of toilet paper on the shelf... Everyone has a different opinion and, as that old saying goes, they all have "the exit port" and many of the opinons stink, but all of those exit ports "stink"...
Exit port on the sewer dump valve/connection.... What did you think I meant ????
