How much water do you REALLY have left?

We boondock in our 2015 Voltage 3800. The limiting factor on how many days we can last is water. We make our electric from solar, and go into the nearest town after 4 or 5 days to refill a propane tank. So how much water do we really have left?
- Our specs say we have a 160 gallon water tank
- I stuffed it full before we left
- We dry-camped for 8 days in the desert
- the 4-led idiot gauge was down to 1 red light (supposedly “empty”)
- when we returned today, I refilled the water to full - with a gallon meter gauge
- it only took 70 gallons
- that means I really had 90 GALLONS LEFT!
- bottom line - the 4 red idiot lights between E and F only measure the top half of the tank!
- someone PLEASE correct me if I’m wrong!

Hard telling what they measure. If they measure anything at all.

I would completely empty the tank via the drain down valve, then use the meter to check the actual fill amount. Camp, then refill. I have a 41-gallon fresh tank, it will get us through a 3-day weekend if we are careful. We carry drinking water separately. They do make a proper gauge set, my preference would be the ones from SeeLevel. There are at least two others on the market that are similar, in that they actually work and indicate what is in the tank.


There is madness to my methods

When our tanks are totally empty. One green lite is still lit. Always been that way. So, flip a coin

Precision is not a term Dutchman understands.
