If a meter will give me reasonably accurate information, which I can

Well, buy a Smartguage then!

Can't a person extrapolate state of charge with a simple voltmeter?

It can be done, IF you have charactorized you battery cells before hand,
and have a good running record of SG vs Voltage on a per cell basis.
Other than that you just "Guesstimating", and that is about as accurate
as a DartBoard.......
