In this video, a few tips and tricks for bringing water to and filling the RV tank at our boondocking campsite. I demo myself filling my Aquatank water bladder at a State Park water spigot that doesn't have any threads for the hose. for that, I use a rubber connection device called a Water Bandit. So that I know when I have added 30 gallons to my bladder, I use an inline water meter.
Back at the campsite, I use a 12V RV water pump to draw the water out of the bladder and push it through a 3 stage water filtration system attached to my trailer's bumper.
