Re: 2nd Battery or Battery Booster
I've got a 27' Tartan and we use 2 group 31 batteries (upgraded from group 27) for our house and starting bank. We don't overnight enough so our old batteries lasted nearly 7 years, which is decent for battery life expectancy.
The more batteries with the more amp hours (AH) on it the better. Deep cycle lead acid batteries can be found at places other then West Marine, if you have time to shop around.
You won't regret adding another battery to your bank if you plan on doing significant overnightings.
Bring the battery booster along too. It might save your ass one day.
