"what is a reputable make of starter battery that I can use as my Aux. battery?"
If the auxiliary battery is being used to power
accessories such as a
fridge, NONE.
You should use a deep cycle battery for this purpose, preferably AGM type.
what make and type of battery to replace the dying main battery?
As mentioned the Exide Extreme or Century Overlander are good choices.
The Optima is excellent for both starting and deep cycle work, but the price of this battery is excessive. Plenty of cheaper choices around.
Although the Extreme is also rated as a starter and deep cycle battery (CCA & A/H) I am not convinced. I'm not knocking them, I run one myself as a starter battery, but not keen on cycling these down to 25-30 percent too often. That is where the AGM batteries excel.
