When we had our Travel Trailer (40 gal fresh, 30 gal grey, 20 gal blk) I always carried wastewater tote and freshwater jug. Used the tote once to drain some grey. Used the FW Jug many times to add 5 or 6 gals of water for our last nite or so. Came in handy. But our kids were smaller and, well, needed baths more.
Today, in our Class C (43 gal fresh, 41 grey, 32 blk), I only carry the FW Jug. Why? I gave both jugs to the new owner of our TT, and only replaced the FW jug. Worked hard not to need the tote. But then, mostly we camp at places with hookups since we try to stay longer and "tour" or explore the area.
Our plan is when we are at a state park or other for several nites w/ only electric, we do a navy bath (wet wash rag, soap, then rinse with water from shower or usually just another clean wet rag). Not perfect but works for a nite or 2.
BTW, we opted for a hitch mounted spare tire carrier (our hitch is attached to the frame, not thin tube bumper). Would have loved the BAL under frame carrier but went this way. Can still tow a toad or what not.
