We have a 2019 EII with the standard toilet.
Tanks on 2019 were specified as :
Fresh = 30gal - more like 28Gallons
Grey = 30 Gal
Black = 18 Gal (Now 15 Gallons reported in later models.)
The NEWER Specs from 2023 data sheet are shown below:
Fresh Water Tank Capacity
Design Capacity 32 Gal.
Grey Water Tank Capacity
Design Capacity 32 Gal.
Black Water Tank Capacity
Design Capacity 15 Gal.
Use Case: Boondocking sites...no restroom or pit toilets.
We take very short (Navy) showers, wash hair outside or in a basin, and use wipes every other day.
Black: Boondocking the black tank fills between 3-5 days. (If there are pit toilets or other facilities then we can get to 6 days.)
Grey: Typically lasts 8 days. We've not typically had an issue with GREY filling up.
For Boondocking, the toilet really is the limiting factor, and many have specifically chosen the compositing toilet for that reason if they plan to do a lot of boondocking.
