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 ...

wired to produce 24 volts (which I assume would result in less loss over the run to the controller compared to 12 volts)Terminology is confusing. So called 12V panels are typically 18-20V and used for 12V battery systems with PWM controllers. Ditto 24V panels for 24V battery systems which almost no RV has.
MPPT controllers open a new world where higher voltage panels can be used with lower voltage battery systems. My 3x series panels will produce about 100V at 8A. The MPPT controller will convert that to about 45A for my 12V batteries.
Just ideas. You need to determine what works for you considering needs, budget and what fits on the roof, etc.
