Camco 41541 Portable Toilet, 5.3 Gallon Waste / 2.5 Gallon Fresh

The Camco 41541 is a self-contained portable toilet built for boats, RVs, campers, and anywhere a permanent head just isn't in the cards. It's a two-piece design. The upper section holds 2.5 gallons of fresh water and carries the seat, and the lower section is a 5.3-gallon waste holding tank that detaches for emptying. No plumbing, no black-water hookup, no through-hull. You fill the fresh tank, you flush, and when the waste tank is full you carry it to a dump station or a proper toilet and pour it out.

That 5.3-gallon waste capacity is the number that matters most. For a weekend aboard a small cruiser or a couple of nights in a truck camper, it's plenty for two people before you need to empty. Run four or more people through it and you'll be emptying more often, so plan around your crew size. The 2.5-gallon fresh tank feeds the flush, and you'll get a good stretch of flushes out of a single fill before you top it up.

Flushing works off a bellows pump. You press it a few times to draw water from the fresh tank and rinse the bowl, and a pull slide valve opens and seals the passage between the bowl and the waste tank. Slide it open to flush, close it after, and the seal keeps odors and contents down in the tank where they belong. It's simple, manual, and there's nothing electric to fail on you out on the water.

Size-wise it measures 16.13 inches long, 13.75 inches wide, and 16.38 inches tall. That's a compact footprint that tucks into a V-berth on a 25 to 30 foot sailboat, a small RV bathroom, or a corner of a tent or ice shanty. Measure your space first, especially in tight cockpits or narrow head compartments, because the 13.75-inch width is usually the dimension that decides whether it fits. The seat sits high enough for an adult to actually use, not just perch on.

Emptying is the part people ask about. The waste tank separates from the top section, and there's a pour spout so you can aim the flow and cut down on splashback. Take it slow on a full 5.3-gallon tank and angle it right. A few tips from folks who live with these: lubricate the slide valve with silicone spray about once a month so it keeps sealing and doesn't stick, and stick to marine or RV dissolving toilet paper. Regular household paper and heavy TP use is the fastest way to clog a bellows-pump toilet. A holding-tank treatment drops odor way down, and if you're in a small closed cabin, a little 12V vent fan makes a real difference.

The body is beige plastic, easy to wipe down and light enough to move around one-handed when the tanks are empty. It's an honest, no-frills unit. It won't give you the pressurized flush of a household toilet, and it's not meant to be plumbed into a marine sanitation system. What it does give you is a clean, self-contained head you can set down anywhere, use for a weekend, and empty without any hoses. For a lot of small boats, campers, and backup-bathroom situations, that's exactly the right tool.

Storage and off-season care are easy too. Empty both tanks fully, rinse the waste tank, and let it air out before you stow it so nothing sits and stains the beige plastic. If you're winterizing a boat or camper, don't leave water in the fresh tank where it can freeze and crack a fitting. A quick shot of silicone on the slide valve before it goes into storage keeps the seal supple for spring. Do that every season and one of these will last you years.
