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.

Interesting experiment. Now swish those jars around a little.

Probably any single-ply toilet paper that will break up with a little agitation should be OK to use in an RV toilet.

If you're paying $4 a roll you need to find another place to buy TP. 4 rolls of RV TP at Wal-Mart is like $3. I checked out the price before one of my last camping trips and I didn't see enough savings to buy regular TP VS RV TP while having to worry about what will dissolve and what won't.

all TP is designed to dissolve in water. We use our regular Charmin.

We also don't add any of the poo-dissector chemicals.

Oh, but i do regularly use the Calgon/woolite mixture in the black tank to make everything non-stick and extra flow-able.

We've been using Scotts for Septic Systems for years. Priced below the RV TP , available at WalMart and isn't single ply. It breaks down the same as the RV TP and we use it at home as well.

The RV paper I've seen is narrower than home paper and the rolls are also smaller diameter which makes it even more of a rip off.

I do belive any TP that is labeled 'Septic Safe' is the same as the RV labeled product.

We use the regular Scott's 1000pc per roll stuff. It's the same stuff at any supermarket, wallmart, target, etc. It 'disolves' quickly. Try it in your experiment.

Not all RV label TP work the same. I do have a favorite brand that I get at WalMart but it is the higher price package & it seems to last longer too. The other cheaper brand @ WalMart doesn't seem to break down as fast as the Marine brand.

After seeing the test jars at the RV show last October I also would consider using Kirkland brand. Don't know if it makes a difference but they used 1 sheet of each type and placed in same size containers with equal water.

Some household TPs are now coming narrower too.

Great choice for "Living within my means" and camping for one...
