Solar does a better job than I can with a few different chargers available and measuring with meter or hydrometer. You need a solar controller with temp compensation and it needs to have setting functionality to tailor to your batteries.
FWIW, I am charging two banks, a 2-6V bank and a three AGM bank with the single controller.
BTW, it also helps to have a module tilting mechanism if you live in snow country. My single big module will have snow on it for a day after a largish snowfall. The second day, it will have nearly all the snow off.
If I had your setup, I'd run the tender with only the batteries being powered. I'd also keep an eagle eye on how they are fairing. an equalisation procedure during storage would probably bring more longevity. A hydrometer will unfold any lack of battery health.
