You may have hit the nail on the head, bad battery. Terrible smell that can be mistaken for a sewer smell.

Hmmmm! As you know, our resident snake battery oil advisor gives a lifetime warranty to those who follow his advice, but it only applies if you add 4 oz per cell. Any less and you are on your own.

The question is, what is charging your crank battery that would have that result overnight when the engine alternator isn't turning. If your shore power also charges the starter battery, might pay to check what voltage it is putting out just in case.
