Ever run out of fresh water while boondocking?

We always do just as you describe except I carry 6,, 6 gallon containers that do not collapse (usually have plenty of room in the truck bed, which makes it easier to pour into the FW tank. One trip to the water source and I have a full tank again but the real problem is holding tanks. Never have filled the galley or the black but sometime have to do some management on the gray tank. Depending on where I boondock this may or may not be a real problem.
