I have two 12V batteries run in parallel. The connection from the RV has the positive connected to the first battery and the negative connected to the second battery. Should I connect the charge controller in the same fashion (on top of the RV connection)?
Your diagram under RV kits shows the RV connected to one battery and the charge controller connected to the other battery.
Want to confirm correct methodology before I make the connections.

Answer: Both methods are correct. The charge controller is seeing one 12v battery in both cases.
Which charge controller do you have? Be sure to follow the installation manual for the charge controller you have, not the general diagram on our web page.
Feel free to upload a sketch if you need more help with this.
The charge controller is the Morningstar PS-15M 12/24V 15A Charge Controller.
Great.
Section 7.2 indicates that his unit works fine with auxiliary generators (RV Alternator).
Be sure to follow the step-by-step installation guidelines as they are outlined in the manual.
