Is 50 gallons of fresh water enough for boondocking?

Fresh water is the limiting factor for me. If I were to buy another MH it would have at least 80 gals of FW. I have 60 gals now and can go 7 days with two people. When I went out west last year with my son and GS we could stay only about 3 days in one spot which was OK because we were in a traveling mode and wanted to see a lot of the west. Another way to look at it is with just 2 people after 7 days I still had 50% SOC on two GC batteries with no generator usage, but my wife wanted to do laundry and wash the bedding anyway so I would stop at a FHU CG to do laundry, dump and fill and recharge my batteries and then move on to another area.
