Black Tank Fills Quickly......
There are usually 3 or 4 of us when we go camping. On a 7 day trip we will usually have to dump the black 1/2 way through the trip because it's near the bottom of the bowl. When we are leaving after...

A whole roll of TP very obviously won't take more space in the tank than the size of the roll itself (maybe a quart?), and actually much less, since when dry it's mostly air. And if the argument is that it swells up, it only does so with the water which is already in the tank, so that's not increasing the total volume. And what are you supposed to do on these boat trips? Dump the poopy TP overboard, or in the trash bin? Neither is a good solution.
No, actually it isn't. I've been on a number of boat tours where you can't flush the tp for that reason.

Filling a tank too fast is often a matter of training. If you can't use a tree (or off the side) for #1, go then use a very quick pedal to dump it, no more. If #2, fill the bowl with a couple inches of water beforehand (half pedal on most units), which makes it dump faster and keeps it cleaner. A volume of water before is worth more than double the water after. If brown steaks on the bowl bother you, it also helps to line the bottom of the bowl with a couple of small strips of TP.
Although we have more capacity now, in the past we've had no problem going a weekend with 2 people using a 5 gallon Porta-potti in a pop-up. 3-4 people using a 20+ gallon tank shouldn't be an issue.
Nevertheless I consider a 22 gallon black tank to be small. 30 is adequate, 40 is ideal/desireable.
