We have a 25 gallon tote-n-store, but try to never fill more than about half full as it gets too heavy.

"A bad day camping is better than a good day at work!"
I took a slight different (cheap) approach. I bought a number of 5 gallon buckets and lids from home depot. If I need to dump some gray I simply drain into those (I use a sewer cap with a 3ft garden hose attached). Then load into the bed of the truck and port to the dump station.
As they stack I can easily store them in the belly of the trailer once dry.
It's worked great for me, probably a little more work, but spreads the weight and a lot cheaper than one of the totes.
How long will you dry camp? Gray water fills faster than black and is much easier to dispose of. We have used a 10 Gallon for about 30 years. We can go up to 2-3 weeks on Blackwater and when it is full we tote the trailer to the dumpstation. Gray water we dump as necessary. I have a ball hitch handle for our tote tank. As it is small either my wife or I usually just walk it to the dump unless it is far from our site. One thing not mentioned for the larger tanks. Boondocking is usually in areas that have rough surfaces such as rocky or tree roots. Larger tanks can be a backbreaker as it is not always possiple to back the tow vehicle close enough to tow the tank.
For me, Smaller IS better. We have dry camped for months with our 10 gallon tote.
i also have the 32 gal, 4 wheel blue tank. have only used it extensivly once and that was at an army corp CG that we were at for 2 weeks and did not feel like breaking camp and setting up again. between that and the 40 gal FW poly bag it was great.
also have a CG we go to every couple of yrs that has no dump station-they are both 10+ mi away at the 2 entrances of LBL(land between the lakes, Ky) did break camp and dump there, kinda far to drag a tank, but now also have a macerator pump so the next time it will be a different story.
only problem that i can see with them are the cheap tires which i plan to change.

We have the Barker 25 Gal. We use it only for grey water, never for black. I have never stayed anywhere yet where my family and I filled up the black tank.
We usually fill up about 20 gallons or so, and it is just the right size for us to empty about daily and keep Mrs. Slpybear and the cubs cleaned up.
I have a 32 gallon 4 wheel Barker. The smaller sizes would fill too quickly for my liking. Yes it is heavy but it is designed to be towed or pulled not carried. I have no problem filling and towing to dump station. Hard plastic wheels can be loud when towing. Several members have changed original wheels to a nice quiet rubber wheels. I tolerate my blue tote, kind of a necessary evil when camping without hook ups.
We have a 22 gallon tote that works well now that we swapped out the hard plastic wheels for soft rubber (inflated) tires. I found the tank much easier to lift and super easy (comparably) to move around with the new tires on it. Much quieter getting it to the dump station, too. (the mod cost about $15, $5 for each tire and a few for the miscellaneous hardware to make it work.)
