Now that we had our food and drink ready to go, we turned our attention to water. Sure, you drink water, but we normally keep our bottled water in the fridge. We sure aren’t going to use bottled water to wash with. Instead of bulky gallon bottles, we turned to a pair of these Hydras from Rompalicious. The Hyrda dromedary has a 2.5-gallon capacity and is designed especially to hang from this section of a factory Jeep rollcage. With two of them, our on-board water capacity is 5 gallons.
