This wiki has been updated 13 times since it was first published in October of 2016. Although feces and urine may not be the most pleasant of subject matter, figuring out what to do with them when you're traveling in a recreational vehicle is an essential consideration. Fortunately, these black water tanks provide an easy and relatively sanitary way to dispose of your family's waste. We've included both portable models and those intended for permanent installation.

Editor's Notes

June 25, 2020:

When you live at home or visit a lot of public places (e.g. shopping malls and restaurants), you might take for granted the modern facilities responsible for rinsing and flushing your waste away. You probably don't worry about any issues with using a traditional toilet in these places because you know the plumbing system to which the equipment is connected ultimately sends your "business" into the sewer line or septic system. But when you travel for long periods of time in your own recreational vehicle without access to these facilities, the only thing you can do is leverage the RV's waste containment system and keep the stuff stored on board until you find a safe place to dump it. While many RVs have their own bathrooms and waste containment systems, you're still going to need a way to transport it for disposal. Our hope is that these black water tanks will help make that job a little easier.

Both the Camco Rhino and Barker 27844 offer the benefit of swiveling front wheels and tow bars, so you can pull them like wagons and easily transport waste to a dump station. The former of these two models is equipped with gate valves and an integrated tank rinse for effortless emptying and easy cleaning.

Now I realize the Alpha Systems VB22548H looks kind of like the monolith from 2001: A Space Odyssey. While it may not jump start a new age of evolution, its durable high-density polyethylene construction and 33-gallon capacity can definitely withstand heavy use. It can also accept customized fittings.

We've also included the Thetford Smart Tote due to its patented AutoStop fill shutoff, which prevents spills and overloads.

The newly-added Vingli Portable utilizes a venting system that allows for the release of excess air pressure, so you can quickly dispose of both grey and black water. Furthermore, its freestanding design eliminates the need to manually hold it upright.

Finally, although it's a small option, the Barker Original Tote-Along is still a good choice for short trips and transferring a few gallons of waste into a larger container or traditional toilet.
