Within 1 month of delivery I swapped out my OE 12 volt deep cycle for 2 six volt golf cart batteries. I have the same Montana as you with an onboard generator. The two 6 volts fit nicely in the compartment but had to buy a new sealed battery box and change the vent. Along with changing the lights to LED there is enough of power to dry camp for a day or two depending on what you have to do. If you start adding invertors to power Electronics or other 110 volt appliances your time gets shorter.
You will need a better battery monitor than the light system to know when to start your generator to recharge.
