After three days on shore power why do I constantly see a charge of 2 or so amps going into the batteries? Is that normal? Shouldn't they get 'full' at some point?

How big is the bank?
How old is the bank?
Is it possible you have a load bypassing the shunt?
Even when "full" batteries will take some
current. Healthy batteries will drop into the tenth or hundredth of an amp acceptance rate but sulfated batteries can take more for longer...
It is also possible your chargers power supply is simply switching on and off to maintain voltage and not over shoot it. Many chargers have rather poor low
current resolution. Watch the ammeter and see if it occasionally blips off then back on..
