That was an outstanding post! Simply stated, clear, and right to the point.
It was indeed! Thank you so much, @westend! So, I don't need to think at all about stepping down voltage from flooded under the hood to AGM house? That's a lot simpler...
I might add that another inexpensive source of large cabling for use in RV battery setups is jumper cables available in any auto parts store. The clamps on the ends can be cut off and replaced with the heavy duty bolt-on lug connectors available in the same stores.
Yes, that's what I ended up doing for my last project. Most jumper cables are CCA these days, though. IIUC, that is ok if not connecting to pure copper wire anywhere in the run, but unadvisable if we are. I found some pure copper, so I used those.

With small pre made portables you simply open up the panels, fold out the legs and clip the leads to the battery. I wired up a simple portable panel/controller/battery set up this morning in under a hour.
I did not realise it could be so easy :).
I read last night that I should figure approx 1watt of solar to 1aH of battery. But I'd had the impression from research a few years ago that it would take much more than that. Maybe I am mixing up full charge with partial-charge-better-than-nothing?
For 200aH of batteries, how many watts solar would be worthwhile at, say 2 hours of direct sun per day and a bunch of hours partial sun?
You folks all are awesome, and I sure appreciate the help!
