Simplest battery monitor and shunt? Advice for non-expert

Dan in reading your posts and looking at the beautiful photos you always post with them, I believe while all this technology that was posted here while very informative, someone that likes to boondock like yourself, I would just get 2 6v GC batteries with 230amp hrs and not worry about an expensive way to monitor them. Just check voltage when you get up each morning and go hiking for the day and take some more photos. 230 amp hrs will last you a week before you need to recharge.
