Let's begin with your RequirementsStatement.
This gives a reference for your use, souls aboard, your destination(s), your preferred duration of boondock, various and sundry.
Your RequirementsStatement -- always evolving -- also gives you an opportunity to tune your goals.

re -- fresh-water tank
Although some live-aboard folk are comfortable with baby-wipes and alternative 'grooming standards', we need a daily shower.
.
Accordingly, we carry a ton of water.
An excessive amount of water.
Some might say we are obsessed with water.
Our battle-cry as we wade into the fray -- "Wet-Heads, Unite!".
.
In our introduction with plenty of portraits, plus our reasons for our decisions, we describe our water kegs.
After a half-century of make-do camping in lesser rigs, we built our ExpeditionVehicle.
Based on our experience, these kegs offer advantages over a single yuge tank:
* modular
* some remain in-service in camp while others go to town for re-fill
* one keg can go to the picnic table or campfire
* a keg can be loaned to a caravan chum
* if one gets stanky, the others remain in-service and can clean the problem child
* our standard load is seven kegs, a total of thirty-five gallons... and with our massive GVWR, we can easily add a dozen more.
.
Our fresh water stores in retired five-gallon stainless-steel Pepsi kegs.
These are popular with home-brewers of beer and kombucha.
.
We workkamp near Eugene, Oregon.
This area has multiple retail sources for components to refresh and rebuild their very simple design.
A few O-rings, a couple brushes, and your kegs are set for years of pretty much zero maintenance.
Manufactured by Cornelius, Pepsi kegs are aka as 'Corny kegs'.

Staying with the 'water' theme, later sections describe our shower Gizmo, with its 'up'-grade add-ons.
.
You mention your rig is a partial conversion.
One advantage to building:
* you are intimate with your components and systems.
You can usually isolate or work-around minor issues.
.
Compare this to a factory RecreateVehicle, enormously complicated components cobbled into enormously complicated systems... all cleverly concealed behind walls and floors and the built-in 'entertainment center' with electric fireplace and wine-chiller.
.
As you might imagine, we built our rig with the minimum of gadgets and do-hickies:
* zero plumbing
* pretty much zero electric
* zero built-in lights
* zero holding tanks
* tiny interior
* Cummins mechanical engine (zero computers)
* Commercial Off-The-Shelf (COTS) everything, zero purchases from the RecreateVehicles store.
.

c)
Time to move on?
Grab a few kegs... new from the store or used off Craigslist.
Sanitize, remove the labels if they bug you, replace the O-rings if needed, and you are ready to travel and boondock the next day!
.
.
d)
Another point about full-time live-aboard:
* zero pressure.
Any time, any direction, any destination.
.
And you can shower twice a day if you want...
