Duraflex Gator® Portable Waste Holding Tank | 21903G | 29 Gal | 2WH

Extend your camping stay without breaking camp using the Duraflex Gator® Portable Waste Holding Tank (Part #21903G). 29-gallon 2-wheel portable RV waste tank — blow-molded UV-stabilized HDPE construction, 12" solid rubber wheels, heavy-duty tow handle, and included Gator® sewer hose accessory kit. Made in the USA. Meaningful for extending dry camping when your RV's built-in waste tanks fill up.

⭐ 29-Gallon Capacity — Extended Camping Without Breaking Camp

Standout use case: when your RV's built-in black or grey water tank fills up mid-stay, roll the Gator® tank to the dump station instead of packing up the entire RV. Meaningful for:

• Extended stays at sites without full hookups
• Boondocking / dry camping
• Overflow capacity during heavy-use trips

⭐ Blow-Molded UV-Stabilized HDPE Construction

Standout durability vs cheaper portable tanks:

• Blow-molded HDPE — seamless, leak-resistant construction
• UV stabilized — resists sun damage and long-term outdoor exposure
• Abrasion resistant — handles the drag/roll wear that shortens cheaper tanks' lives

⭐ 12" Solid Rubber Wheels + Ergonomic Design

Meaningful ease-of-use features:

• 12" solid rubber wheels — roll easily over gravel, grass, uneven terrain
• Low-profile ergonomic design — comfortable to handle
• Padded grip handle — comfortable for the roll to the dump station

⭐ Heavy-Duty Tow Handle

Standout feature for longer distances: heavy-duty tow handle allows the tank to be hitched to a motorized vehicle for secure transport. Meaningful when the dump station is well beyond an easy walk from your site.

⭐ Vented Quick-Drain System

The vented quick-drain system helps the tank fill and empty quickly — reduces the time you spend on waste management.

Integrated Garden Hose Inlet for Cleanup

Cleanup is straightforward — included garden hose inlet lets you flush the tank after each dump.

Includes Complete Gator® Sewer Hose Accessory Kit

Meaningful value-add: each Gator® portable waste tank ships with a Gator® sewer hose accessory kit — everything you need for clean, complete sanitation setup out of the box.
