As long as you purchase the 2nd battery with the same Mfr/Make/Model you should have no issues. Example: most TT's come with a 12 volt Interstate RV/Marine hybrid batteries (thicker plates than a car battery but thinner plates than a true deep cycle battery) and are a size 24, I believe 85Ah. As long as the second battery is identical to the existing one, there will be no issues.
Yes, the TT's battery charge controller only sees 12VDC source connected to it. Most of the newer TT's have charge controllers capable of pushing out 40 amps (not that I have ever see it), but that is what they are rated for and they go through 3 modes to properly charge them. I would make sure that both batteries are at full charge before connecting them together.
The only suggestion I would make, is use 4 or 2 gauge wire connecting the 2 batteries together.
Below is the proper way to wire (2) 12 volt batteries in parallel.
just my thoughts,
