Adding a 2nd Battery?
Would it be a problem if I connected a second battery to the current battery. My Class C had 2 Batteries, Class A only has 1.

2 batteries work better together if they're the same brand and age, but I've seen people hook just about anything together.
I keep hearing this... IF you put a pair of GC-2 (six volt) in series you get 12 volts at around 220 amp hours (Give or take a bit depending on specific battery) you can safely use HALF this power.... And yes they should be "Twins" (Same age, type, make, size, and so on)
With 12 volt's in parallel. Most are MARINE/deep cycle or MARINE/rv which means you can only use about 1/4 the capacity. but they need not be identical. There is an advantage (Slight) or disadvantage depending... But I run a mix. currently one each Group 27 29 and 31 with a pair of GC-2 all in parallel. they work it out.
Lots of "Oh this will happen" or "That will happen" It does not. The batteries form a perfect commune.. The ultimate Socialist society.. (Works for batteries. I won't comment about where it does not work) in that when charging each takes what it needs and when working gives what it can.. they all remain at precisely the same state of charge relative to each other (If one is at say 90%. then all are) at all times.
Less one fails.
