28 gallon portable RV waste tank, barely used - maybe 3 or 4 times total. Has the oversized no-flat wheels, built-in gate valve, tow adapter, and comes with the full accessory kit - sewer hose, grey water hose, elbows, and storage caps, all included (see photos).

New these run $180-220, this one’s basically like new, just dusty, for way less.
