Downtheroad's post is almost correct, however, it is better to have positive and negative off opposite ends of the 12 volt system. The first battery in the drawing will get the best charge.
Of course this is only my opinion!
The condition of the batteries and guage of the wire will make a bigger difference than which battery is connected closest to the charger. The resistance of the wire between the batteries is almost unmeasurable. If two lights are turned on, does the one closest to the battery glow brighter ? The same laws of physics apply to both charging and discharging.
EDIT: If the batteries were 50 feet apart and connected with a light guage wire, the connection sequence might make a difference, but at 2 or 3 feet apart and connected with the proper guage wire there is no measurable difference.
