Just what is "RV" toilet paper??
I hope this has not been covered before.
We are wondering exactly what "RV" designated toilet paper is. Does it meet some government mandated standard? Does it meet some RV industry regulation? Does it have to go through some rigorous testing before it is allowed to have an "RV" designation? Or do TP manufacturers simply slap an RV label on it and get away with it?
After having been to an RV show last fall and seeing a demo., we did a TP test of our own with 4 different brands in water to see what happened. Very interesting results. The first photo below shows the 4 test samples in water. From left to right is "Kirkland" from Costco, another Costco one (but forgot to record the brand), Thetford and then Valterra. IIRC, it took about an hour before you could see something happening. At 24 hours, there was no further visible degradation of the TP.
The 2nd photo shows the Valterra brand after "dissolving" and the 3rd is the Thetford TP. You can see how the Valterra turns to a sort of mush but the Thetford does not and the sheets stay connected and there is little degradation of the sheets.
What we found is that the Kirkland and Valterra "dissolved" but the Thetford and other Costco brand did not. Are we being duped by TP manufacturers? Why pay up to around $4 a roll for RV TP when you can get some from Costco for 50 cents a roll and works great?
So from now on, we are going to buy the Kirkland stuff. For those who might be experiencing problems with cleaning tanks or level sensors not reading correctly, it might be worth switching brands and seeing if that helps.
