I have found that using a water-mattress style water tank for transporting water works great while boondocking. Usually, the difficulty in dry-camping lies in transporting the water on the roof and trying not to lose any while the vehicle is in motion. Additionally, the water-fill inlet on my trailer is about chest-high, making the gravity flow painfully slow.
My solution was to incorporate an aerator pump. The unit was fitted with pipe thread to garden hose adapters on the suction and discharge fittings. The pump draws 1.7 amps at 12 volts DC and the electrical supply is provided by a connection on my truck.
The pumps moves about 2 to 3 gallons per minute from up to about 50 feet away, and requires no lifting of heavy jugs for refilling the RV. The mattress holds about 35 gallons. Also by placing the mattress in the bed of the truck, you can drive at highway speeds without worrying about spilling water.
