Holding Tank Capacity

[ButtercupWa]

The spec sheet says my 2018 C-28 has a 30 gallon holding tank, and I have been unsuccessful in finding information on the typical amount of water used per flush by the Raritan electric toilets on the C-28. Trying to do some math on how many person-days I can get with my holding tank. Thank you for your comments in advance!

We have a C30 with 40 gal tank. We were just out for 8 days. We pumped at day 6. 2 adults and a 8yr old.

We usually get 1 gallons per person per day.

3 adults onboard, our 30 gallon tank lasts us 10 days. So by day 7 or 8 we are looking for a pump out.
