We just got back from a 4-day trip with two grandsons, so my water pump setup got a good workout -- the 11-year-old does pretty well with water management, but it's hard to impress the idea on a 5-year-old
The 11-year-old made all the trips to the hydrant to fill the water jug. Great kid!
Anyway, here are two pics of my setup. When not in use it lives on a shelf in the cap on my truck. I couldn't find a spot to keep it in the camper, and our storage bay isn't great.
