For the effort I would still go 100 watts. Yes the 30 might be fine. Yes the 7-10 watt might be fine if battery is fully disconnected and just to maintain a full charged battery. With 100 watts you can arrive with a low battery, close up the RV and the battery will be fully recharged in a couple sunny days. No more effort to mount a 100w panel vs something smaller.
Yes you must get polarity correct. Pretty sure the ZAMP is just a common SAE 12v connector available at most automotive or electronic supply stores. Make your own pig-tail adapter to connect as needed.
At this low power you can connect to one battery if that is easiest. Best is positive to one battery and negative to the other same as you main RV cables should be attached.
Thumbs up
