Solar - Upgrade or replace outright?
The new-to-us coach has a small solar panel system. I would like to upgrade it to the point where I could reasonably hope to capture 50 or 60 amp-hours per day in light conditions that are less than ...

Here's some links to sites with a wealth of solar info:

Keep all wire runs as short as possible.
It's best to install the charge controller as close to the batteries as possible.
An MPPT charge controller is you best option but they are costly. If your panel voltage is greater than 12 volt nominal it is your only option.
Most panels larger than 120 watts are 24 volt nominal.
The higher the voltage into the controller the better. Panels connected in series must have the same specifications. Make sure that the charge controller can handle the highest voltage produced by the panels. This will be the Voc (voltage open circuit) of the panels. Typical Voc for a 24 volt panel is close to 40 volts. Connecting two panels in series would produce about 80 volts.
