Boon Docking for 5 days

So we hit up some BLM land for camping over the Memorial Day week end and spent five days at a BLM Campground. They were nice camp sites with a fire ring and shade. There were pit toilets and no water. In our group there were three of us. One with minimalist type camping trailer called a Cricket and the other with Sprinter Van Conversion done at a local place that does this type thing. We were the "spoiled brats" in our Creek Side................And strangely enough both the vehicles with the small Eco-foot print..............Ran out of water....Rookies. What kind of boon docking trailer has 10 gallons of fresh water!!!! We came back with a third of a tank of water and room left in the grey and black tank. Solar kept the 6v series batteries up perfectly. We run two 12v C-Pap machines at night. Had a great time!
