I have a 50 gallon grey and a 28 gallon galley (50 gallon black)
Have a 35 gallon 'tote' used it 3X. PITA ---- heavy to hand drag thru sand, gravel etc (sites where no sewer were also rough/undeveloped) from side of RV out to behind truck. PITA to drag it down to dump station....snails crawl so it doesn't fall over, then line it up and dump.
My 'light bulb' moment.....can go full week before needing to dump.
It is easier to hook up 5vr and go dump ALL at one time then set back up OR just dump on way out.
Others seems to like/use the totes.........I hated messing with it.
A larger capacity would have been even more PITA
