Solar maintainer.
The depth of knowledge about all things solar on this forum is formidable indeed. So I want to take advantage of a small amount of it. Can a 10 watt solar battery charger keep an average RV 12 volt...

Easiest way, charge the battery fully and remove the negative battery cable. The battery will fine, it will not freeze, the self discharge rate will be minimal. Charge it up before next use.
I have done this on my motorhome 6v and 12 vote batteries for years.
The reason I brought this whole thing up is the new-to-us toyhauler came with a 5 watt solar maintainer, which in all honesty, didn't seem to do much to keep the battery charged. But, anyway, it fell over and broke the glass, now I'm trying to decide if I want to replace it or just forget it.
