Premium portable waste tank saves time, effort and hassle. When your holding tanks are full, just empty them into a SmartTote instead of moving your RV. The PermaStore self-storing sewer hose stays connected at bottom of tank, making use a breeze and hose storage mess-free. Just pivot and extend the heavy-duty hose up to 5' to fill or empty tank. The hose stores neatly onboard in a cradle which protects hose and cap. AutoStop level gauge/valve stops flow when tank is full, preventing messy overfilling. Larger 18, 27 and 35 gallon LX models have 4 wheels and a stronger, heavy-duty pivoting tow handle that hooks to a ball hitch for easy towing at up to 5 mph and stows flat for storage, so they require no heavy lifting Rugged 8" outboard wheels provide plenty of ground clearance for easy rolling over any terrain. No extra accessories to buy--includes all necessary hoses, bayonets and sewer hose cap. 35.5"L x 19.75"W x 14.5"H.
