|---|---|---|---|---|---|---|---|---|---|---|
| Construction | The 11 L food-grade LDPE jug has two openings, an included spigot and quick-connect fitting, removable handles and tie-down guides. [1] | The 7 gal/26 L rigid container has a vent cap, molded handle and reversible hideaway spigot. [4] | The rigid non-insulated 6 gal container has top and side molded handles, a pull-up vent and a long-pour spout that stows inside. [7] | The 3.5 gal HDPE brick has an easy-grip handle and wide gasketed lid; the standard package is a two-pack. [10] | The 2 gal BPA-free water pack includes a pour spout and works with RotopaX mounting systems; a spigot kit and mount are separate. [13] | The 5 gal/20 L water-specific military container uses food-grade, BPA-free material and is offered for camping and off-road use. [16] | The flexible 10 L nylon/TPU reservoir has a wide mouth, flow-control cap, adjustable strap, lash points and included shower fitting. [19] | The foldable 20 L polyethylene cube includes an integrated handle and tap. [22] | The 8 L flexible TPU container has dual baffles, a wide Plug-N-Play cap, dispensing tap, webbing handle and lash points. [25] | The 6 gal/23 L rigid water-only jerry can has an angled handle and included reversible three-piece pour spout; Reliance calls it short-term storage. [28] |
| Packed size | The maker describes a shape intended to fit behind a vehicle wheel well but does not give exterior dimensions in the product copy. [2] | Reliance lists 11.5 x 11.25 x 15.75 in exterior dimensions for the 7G version. [5] | Igloo lists exterior dimensions of 13.82 x 7.32 x 20.63 in. [8] | WaterBrick lists a 9 x 18 x 6 in body and a 3¼ in lid opening. [11] | RotopaX lists 18 x 14 x 3 in exterior dimensions. [14] | Scepter does not state exterior dimensions on the product page. [17] | Sea to Summit lists 13 x 5 x 3 in packed size for the 10 L version. [20] | GSI lists 10.5 x 10.5 x 2.5 in measurements for the 20 L model; the page does not explicitly call these filled dimensions. [23] | HydraPak lists 14.8 x 7.8 in dimensions; it says the body collapses flat when empty but gives no folded thickness. [26] | Reliance lists 14.8 x 6.6 x 19.15 in exterior dimensions. [29] |

Choose the container around its place in the vehicle
Measure the storage slot before choosing capacity. Dometic provides tie-down guides for a wheel-well position; the RotopaX has a 3 in deep mountable form; the WaterBrick is 6 in high. Each solves a different packing problem. [1] [14] [11]
Decide whether to pour, tap or mount
The Aqua-Tainer and Water Cube include dispensing taps. Igloo and Desert Patrol use pour spouts, which require tilting their larger filled bodies. RotopaX includes a pour spout, but its mount and spigot are separate purchases. [4] [22] [7] [28] [13]
Plan for cleaning and drying
Dometic lists two openings for filling and cleaning, and WaterBrick lists a 3¼ in lid opening. Sea to Summit and HydraPak offer flexible bodies that need thorough drying after washing. Check the maker instructions before using any container for drinking water. [1] [11] [19] [25]
