Dumping your RV tanks can be a hassle, especially if it requires packing up your entire campsite. Luckily, portable waste holding tanks help smooth the process. We’ll compare two, the Camco Rhino vs Barker Portable RV Waste Holding Tank. Let’s get started!

Camco Rhino versus Barker at a Glance

Camco and Barker make two great portable RV waste holding tanks. Both of these make dumping your tanks more convenient, especially when you don’t want to pack up your entire campsite. 

Take either tote to your nearest dump station to get rid of waste. The four wheels make them easier to pull, but both can also hitch behind a truck. You do need to go slowly, though, about 5 to 10 mph.

Both can be bulky when stored. However, you’ll appreciate the convenience when you need it. These portable waste holding tanks appear pretty equally matched. The winner in the Camco Rhino vs Barker Portable RV Waste Holding Tank comes down to the details.


Let’s take a look at a few key characteristics of each portable waste holding tank. These factors could sway your decision.

Ease of Use

The tanks use an identical process for filling and emptying. They both have the same build styles to make it easier for towing and maneuvering a full waste tank. While they are quite alike, there are a few ways that Camco separates itself from Barker to win this category.

Camco does the user a major favor by including a high-quality sewer hose and sewer connections for emptying the tank. Camco gives you everything you could need to not only fill the tank but also empty and clean it. In terms of ease of use, we think Camco’s Rhino has the edge.


The Barker tank’s wheels separate the two tanks in this category. These thick and inflatable rubber tires give it an edge over Camco’s Rhino tank. While the Rhino has extremely durable plastic wheels, that also means a rougher ride than the Barker tank. In terms of towing, the Barker Tote takes the cake.


Both tanks can hold a tremendous amount of gray and black water. The Camco Rhino’s largest holding tank offers 36 gallons of capacity. However, the Barker Tote Tank has an even more impressive 42-gallon capacity.

Thirty-six and 42-gallon tanks will weigh 300 pounds or more when full. Despite their construction and wheels, maneuvering full waste holding tanks can be tricky and cause injuries. While getting the largest waste holding tank possible may be more convenient for dumping, keep weight in mind. Because the Barker Tote has the largest capacity, however, it wins this category.


The largest Camco Rhino holding tank (36 gallons) costs $260-$270 but comes with a good amount of dumping accessories and tools. The largest Barker Tote Tank (42 gallons) costs $330 or more, and users have complained about cheap hoses and attachments.

Both are costly investments. Users want both the tanks and their accessories to hold up over time. Therefore, we’re giving Camco the win because of its excellent quality and value.
