One battery with no loads on it, or parasitic loads from the RV too?

With. Because I'm bound to forget to disconnect the loads.
you have to be more specific. The term "parasitic loads" may include a lot of things. Most often it's a clock radio - can be anywhere from 1 to 7 Ah in 24 hours, plus detectors - those draw very little. Some people have huge TV set that draws some on standby. Some have 2000W inverter idling 24/7 even when there is nobody home. Who knows...
If you are really unsure, start with 20W solar AND controller, and see where it gets you. 3W-5W is only enough to compensate for self-discharge of "wet" battery in absence of any loads, not even a clock radio.
