Barker Mfg Water & Waste Tanks: The RV Industry Standard for Portable Holding Tanks

Barker Manufacturing has long been recognized as a leading name in RV portable waste management. Within the Water & Waste Tanks category, Barker's reputation is especially well-earned — the brand has built a loyal following among RV enthusiasts and full-time campers who demand reliability, durability, and smart engineering when it comes to handling black and gray water on the road.

The Tote-Along Line: Purpose-Built Portable Waste Tanks

Barker's signature product in this space is the Tote-Along series of portable waste holding tanks. Convenient to store and transport, these portable tanks range in size from 5 to 42 gallons and are available in 2-wheel and pneumatic 4-wheel designs, with all accessories included in a hardware kit and every tank arriving completely assembled. That last detail matters — there's no puzzling over loose hardware at the campsite.

The 4-Wheel Tote-Along is particularly popular among RVers with larger black water tanks. The attached tow bar fits over a hitch ball mounted at the back of a vehicle, allowing for easy transportation of the tote to a dump station. This means you can stay parked at your site and simply tow the filled tank to a dump station rather than breaking camp entirely. Constructed from blow-molded polyethylene, zinc-plated steel, and aluminum, each 4-Wheeler is equipped with a heavy-duty 3" conventional sewer valve for ease of use, with a front-mounted double wheel that swivels for easy maneuvering on a heavy-duty, extra-large mounting plate.

Smart Construction Details That Set Barker Apart

Barker's engineering choices reflect decades of refining these products based on real-world use. The pneumatic wheels feature axle bearings with grease fittings and premium 50 PSI and 30 PSI wheel options — a level of mechanical detail that makes a noticeable difference rolling across gravel, grass, or uneven terrain. Each tank is equipped with 3" and 3/4" caps, a full-tank indicator, and a tow handle, arriving almost fully assembled with only the handle requiring attachment.

For fresh water needs, Barker's Water Tank line is equally well-considered. These non-toxic, food-grade polyethylene water tanks are tasteless, odorless, and rust-proof, with all inlets made of barbed hose fittings — no threads to strip. That thread-free inlet design is a practical touch that extends the life of the tank and eliminates a common point of failure.

Warranty You Can Count On

Barker Manufacturing offers a two-year extended warranty against defects in materials and workmanship on all Tote-Along tanks, a reflection of constant improvements in mechanical design and assembly quality. This goes beyond the standard one-year warranty found on most RV accessories and signals genuine confidence in the product's build.

Choosing the Right Barker Tank for Your Rig

Four sizes of the 4-Wheeler line provide a tank to accommodate virtually all sizes of black water tanks and storage areas in any RV. Whether you're driving a compact camper van or a full-size Class A motorhome, there's a Barker tank sized to match. The 2-wheel Original Tote-Along is ideal for tighter storage spaces or weekend campers, while the 4-Wheel pneumatic models are geared toward extended stays where capacity and ease of transport are priorities.
