Best RV Portable Waste Tanks

Capacity looks like the headline number and is actually a weight problem, because sewage weighs roughly 8.3 pounds per gallon. That makes a 15 gallon tote about 125 pounds when full, a 21 gallon tote about 175, and a 32 to 36 gallon tote more than 260 pounds of dead weight you are dragging by a handle across a gravel loop. Pick the size against your black tank and your own strength, not against the biggest number available: two trips with a 21 gallon tote is easier on everything than one trip with a 36. Wheels are the second thing that separates a usable tote from a chore. Pneumatic tires roll over gravel and grass but go flat in storage, while no-flat solid wheels never need air and transmit every bump, and four wheels track straighter than two when the tank is heavy. A built-in gate valve on the outlet is worth insisting on, since without one you are managing flow with the sewer hose alone. Check the fill and vent arrangement too: a proper vent lets the tank fill and drain fast, and a threaded sewer connection means your existing three inch hose and fittings work without adapters. Storage is the detail people forget, because a full-size tote takes real space, and a bumper mount holder gets it out of the pass-through. Storage compartments for hoses and gloves are a genuine convenience.
