Shady, there are lots of ways to get around small tanks. Our Lance lite has only 18 gal. fresh and we’ve never run out or even used all of it when boondocking. We can now go 6 or 7 days without tanking up or dumping the black. It’s a paradigm shift. We take very ‘GI’ showers, sitting on the pot with a dishpan on the floor and quick everything. We can get by with less than a gallon at shower time. I then dump the semi-grey water outside. Same with any silverware or dishes we use: Little water and throw the grey water outside. Although now, since water is more valuable than paper we use paper plates as much as possible. We carry up to 48, 16 oz. bottles of water for drinking. I have 5-one gallon sturdy water bottles in a floor cabinet for coffee and cooking water. No milk cartons for water: too flimsy. Really the biggest obstacle to extending your ‘off grid’ time in the T.C. is the capacity of your black tank. You can get by, but it requires rethinking how you do business. We also have an outdoor shower for remote camping and a great little gizmo: a pop up shower enclosure. Wonderful in warm climes and boondocks. None of the grey water goes into the black tank. I do much of my elimination outside. Jeanie prefers the privacy of the white box. I think having a solar array is more important when off grid. One last thing: if you plan on going south of the border for any length of time, consider the availability of ultra low sulfur diesel fuel. I think 2006 or 07 was the last CTD to not require a pee canister (DEF tank) and other smog related measures. The internet has a plethora of info on beating the DEF tank in Mexico.
