Top 3: Best RV Portable Waste Tanks For Black & Gray Dumping

When off to camp or boondocking, an RV Portable Waste Tank aka Turd Toter comes in handy when you need to dump your grey and black holding tanks without moving your RV.

Here we highlight the best RV portable waste tank (or RV sewer tote) for your “belongings”. They come in 2 and 4 wheel models and various sizes.

You’ll notice that 4 wheelers dominate the list we reviewed, that’s simply because 2 wheelers can be harder to haul around. Portable waste tanks are heavy when full and you don’t have to heave 4 wheelers vertically.

4 wheelers like the Barker Tote Along roll flat, horizontally. 2 wheels are best for pop-up campers or travel trailers with smaller black or grey water tanks.

A Portable Waste Tank is a transportable human waste container attached to your RV toilet which allows you to remove waste quicker than visiting a dump location and connecting a sewer hose to get rid of your poop.

It’s simply a great way to keep your trips to the campsite or local dumping location at a minimum.

How Long Will a 15 Gallon Black Water Tank Last?

A 15-gallon black water tank will last 5 to 7 days for solo travelers and couples. Larger groups, families, and travelers with children should expect their black water tanks to last less than 5 days.

Of course, if you use the bathroom more than the average person, you’ll need to empty it sooner.

How Long Will a 30 Gallon Black Tank Last in an RV?

A 30-gallon black water tank can last 7 to 14 days. This depends on the frequency it’s used and flushing procedures.

As a rule of thumb: if it starts to smell, it’s time to dump. We want to avoid the dreaded poop pyramid.

Often times it’s the tissue that can increase dumping frequency, even the easy-to-tear ones.

Where and How Do You Store an RV Portable Waste Tank?

  • Tractor Trailer (TT) Storage: A small tote can fit in the front storage of a large trailer.
  • Inside the RV: When not in use keep it sealed and clean until it’s needed.
  • Under your RV: Underneath the RV or TT is perfect storage space. Use strong bungee cords to hold the tank up and out of the way.
  • Put The Ladder to Use: Many RVs have a ladder on the back so you can climb onto the roof. Attach the portable tank there with strong bungee cords or rope.
  • The Back Bumper: You can get a hauler or attach it to your back bumper with a little DIY ingenuity.

Can I Dump RV Tanks at Home?

Yes, you can dump RV tanks at home. It is perfectly legal to dump RV black and grey tank matter in approved residential sewer systems.

If you are worried you may be breaking any laws, do a double-check with your local ordinances and restrictions. However, essentially, the gray and black water in an RV tank is the same as the waste that comes from your house.

Make sure you aren’t dumping into a storm drain. Turd Totes can be dumped in your toilet at home.
