Is 50 gallons of fresh water enough for boondocking?

X2 on the bladder. I have a 60 gallon and have had it on my utility trailer, on tailgate, very back of truck bed, off to the side of the hitch in an irregular cavity and in the backseat. It's tough as heck and folds into a 12x12x3 inch box. It's great to go get 70 or 80 at one time. I have never been to an RV park that could charge me too much for water or dump when I'm sitting for free just about all the time.
