We haven’t even picked it up yet but just bought a 2000 Prevost Featherlight two slide and two full bath rig.
My question is how much water storage do we have?
Just curious if anyone may have ever heard of one like this?
As soon as I have possession and hopefully the manual will let me know, In the mean time if anyone knows anything please share!
Thanks,

Since most buses are custom builds, I doubt that anyone will have an exact answer for you. Maybe close but not a for sure thing. Fingers crossed for the manual. If you can see the tanks enough to measure them, that is what I would do.

I will be picking up the bus in about two weeks and will be driving back to California. I will report back with what I find, and hopefully that it will be a very uneventful trip.

One way to be absolutely sure of your water tank capacity is to measure the tank. Yup! that tank is pretty much hidden toward the center of the coach. The tank should be staring you in the face in the plumbing bay I'm guessing. If it is a liberty it will be front and center. It might take a flashlight and a tape measure to se the end of the tank hidden in the bowls to get the length. with and height should be staring you in the face.
1st: measure height, width and length.
2nd: multiply the 3 measurements together Volume = L x W x H Example: If a tank is 10 feet long, 5 feet wide, and 4 feet high, the volume is 10 × 5 × 4 = 200 cubic feet
3rd: If your dimensions are in feet, the volume will be in cubic feet.
4th: Multiply the cubic feet by 7.48 to convert it to gallons: Capacity (Gallons) = Volume (cubic feet) × 7.48. Example: 200 cubic feet × 7.48 gallons/cubic foot = 1,496 gallons.
I used this formula since nobody even Liberty was sure of what I had. They sent me this formula. As it turns out I have a 140 gallon tank.
That goes to show you changes that can go on when a customer builds a new coach. In my case the customer may have wanted a extended diesel fuel tank in my case and the water tank was reduces, who knows!
I hope that helps.

If your home is on metered city water you could use the lazy man’s way.
Note the gallons on the meter, make sure no one in the house uses any water (I.E.flushing the toilet), fill the tank then read the meter and do the math.
My tank is 160, gray & black are 80 each.

There are a variety of inexpensive meters, I got mine from Amazon, which will measure the water put in your tank. Drain the fresh water tank, refill and check the meter. I purchased mine initially to check my tank monitor accuracy.
