Connecting to the positive on battery one and negative on battery two (batteries attached in parallel) is the best way to balance the load and charge... Electricity follows the path of least resistance - so when connected to a single battery - will draw more heavily from it.
While I would expect more overall life from the batteries keeping the load evenly shared - I don't expect that will add much to the single discharge capability. You may need a bigger battery bank as well...
What is the AH capacity of the batteries, and what is the load you are drawing? (2000W inverter is its capacity - but what it draws depends on the load it is powering.)
