Camco TST 1-Ply RV & Marine Toilet Tissue, 4 Rolls

If you've ever snaked a clog out of a boat head or watched a black tank sensor read full when it isn't, you already know regular bathroom tissue has no business in a marine or RV sanitation system. Camco's TST 1-Ply Toilet Tissue is built for exactly this job. It's a single-ply paper that breaks down fast in water, so it moves through your holding tank, hoses, and macerator the way it's supposed to instead of balling up and causing trouble.

The whole point here is dissolve speed. Household toilet paper is made to hold together when it's wet. That's great at home, where everything flushes straight to a municipal sewer. On a boat or in an RV, that same strength works against you. Paper that doesn't break down packs into the tank, coats the level sensors so they read wrong, and chokes the pump on pump-out day. This TST tissue is designed and approved for RV and marine use, so it dissolves quickly and helps clear the system clean.

It's septic tank safe and biodegradable, which matters for more than just your own plumbing. Whether you're running a portable cassette toilet, a standard black tank with enzyme treatment, or a full marine sanitation system, fast-dissolving paper keeps the bacteria and chemicals doing their job instead of fighting a wad of pulp. And because it's got no dyes and no added perfumes, it won't throw off your tank treatment or leave residue in the bowl. That keeps odors down and your next dump easier.

One ply is the right call for sanitation systems, and it's not about being cheap. Fewer plies mean faster breakdown and less mass in the tank. You'll go through it a touch quicker than the plush stuff from home, but that's a fair trade for a tank that empties clean and sensors you can actually trust. Each pack gives you four rolls at 280 sheets per roll, so there's plenty to stock a weekend trip or keep a spare under the sink. Stick with one ply and your pump-out day stays boring, which is exactly how you want it.

This is the tissue we reach for on just about any boat with an enclosed head, from a center console with a portable toilet to a cabin cruiser with a full sanitation system. It's just as at home in a travel trailer, fifth wheel, or camper van. If your setup has a holding tank, a macerating toilet, or a vacuum flush system, this is the paper that keeps it running clean. About the only place you don't strictly need it is a composting toilet that asks you to bin the paper separately, and even then plenty of folks still use it.

Here's a quick way to prove it to yourself. Drop a couple of sheets in a clear jar of water, put the lid on, and give it a few shakes. Marine and RV tissue like this one falls apart into a cloudy pulp in seconds. Regular paper stays in one piece. That's the difference your holding tank feels every single trip. It's a 30-second test that'll settle any doubt, and it's the same reason seasoned boaters and full-timers won't keep anything else in the head.

Storage is easy too. The four rolls are a standard size that fits a typical RV or boat toilet paper holder, and they stack neatly in a head compartment or galley cabinet without hogging space. Buy a few packs at once and you're set for the whole season. For the price of a cheap clog or a pump-out that won't cooperate, the right paper is some of the best insurance you can keep aboard.
