Basic battery charging and solar question
I have a Surveyor 245BHS with 2 6v batteries wired in series. The RV dealer told me that when I'm plugged in to charge, the trailer doesn't recognize when the batteries are fully charged and will kee...

300W? I think SMK is right.
fridge in LP mode needs 12-15 AH a day, some detectors, LED lights, pumps, DW wants to run kitchen exhaust for an hour, or both of you want to run bathroom fan every time you take a shower or need a toilet just after somebody else had used it...
Total 20-25 AH a day.
100W panel, 6A max in a good sun (hm... in PNW? just look at this summer) - alright, "assuming" a good sun and no trees (no trees in PNW, really?) - alright, "assuming" a good sun - expect solar harvest 20-30 AH a day.
Yep, 100W won't be enough on some (or many) days. No problem if you boondock 2-3 days at a time, battery will gradually drop towards 40-50% by the day three. Big problem if you boondock for a week and weather isn't cooperating.
But... Portable solar over 100W becomes too heavy and bulky. 300W should better be installed on the roof. Not too difficult, but with what you mentioned about your electricity skills, it doesn't meet your requirement of "simple" either.
