Battery Charging
This may be a silly question but if I understand correctly both batteries are connected---can you charge both by hooking a charger to one or do you have to charge separately?

The driver's side battery is hooked to the alternator, so I put my battery maintainer on the passenger side. Once or twice a year I'll separate and put each one on the big charger, and rotate them back into the truck.

The passenger side it the alternator.
On charging it really depends on what your trying to do with things.
If you trying to equalize them them one at a time on a charger that
is capable of doing an equalize charge. Also if your doing that make
sure that you have a battery hydrometer on hand and check before
you start and during the process.
There is a nice charge start chart on this page

IF one battery has a bad cell it won't take the charge properly and can lead to issues depending upon the type of charger being used.. and which battery (the good or bad one) you connected it to

The batteries are in parallel not series. Even in series it won't matter.
If the cell is low resistance it will heat the battery do to too much current flowing
through it and it will never reach it's full charge state.
The optimum way to charge is to isolate the batteries and charge each
one on it's own and test the Specific gravity of the cells. Add water as needed.
Also a good hard charge will tend to mis the electrolyte much better than a slow
low charge will do. Driving should mix it some too.
Just a bit of both in me
