I "might" be able to answer that question, as I dump mine ever 2 days (or sometimes, every day, depending).
First, I have 3 holding tanks: 1 black, galley, and shower-sink. All 3 tanks are 30 gallon, for a total of 90 gallons of water capacity. My Barker tote is 32 gallon.
If any one of the tanks, by themselves, was 100% full, I'd never overfill the Blue Tote.
By dumping every day, or every other day, I can dump once, all 3 tanks and make 1 trip to the dump station. I suppose I could alternate one tank one day, and the other tank the next day, but it doesn't work out that way.
We can take 6 Navy showers and then I want to dump. So, it's not a matter of the "time" between dumps, it's a matter of the water usage.
My black and grey tanks join together to one outlet. Using a Flush King attachable slide valve, I can back-flush the shower water into the black tank, even if the tank is not full. This cleans out the black tank marvelously without having to use extra water to rinse using the black tank rinser or adding more water down the toilet.
So my steps are to dump the black first. It's usually not all that much. Let it run till it completely quits. (I can see this with the clear section of pipe with the Flush King). I then close the Flush King and open the grey valve and let it florce back into the black tank for about 5-10 seconds. Close the grey again and then dump the black again. I repeat this until there is no more water in the grey tank.
Doing this after 6 showers, and I never overflow the tote. Granted, I may need to make a run to the dump station once a day, and if camping over a week-end, may not need to go at all until we leave the campground completely. But this explains why you'll see me dragging the blue thing ever other day at least.
The tote holds 32 gallon, my 3 tanks all hold 30 gallon each. That's why the multiple trips. The guy you referenced, probably has smaller holding tanks.
