1. Assume an elliptical dome top. But do not enter its height Vo.
2. Instead enter a max. allowed liquid level (this can be the hatch height, or a limit set by the manufacturer) and the corresponding max. volume.
   Calculate Vo from this.
   

Good idea. Now, we only need 4 inputs, instead of 5:

1. tank radius r
2. slant bottom height h0
3. total height H
4. total volume V

With above, we can calculate elliposoid dome height v0, cyclinder height h1:

v0 = 3 * (H - h0/2 - V/(Pi r²))
h1 = H - h0 - v0

Edit: I would avoid using (in, gallon) units, and use (in, in³) instead.
This way, the code also work in other units, say (ft, ft³), (cm, cm³), (m, m³), ...
