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...

Multimeter is a must to have in RV. It's not difficult to learn how to use it.
It will tell if battery is being charged, and - in absence of other means - will roughly tell how charged it is. More accurate than those OEM light indicators.
Important is to measure "open circuit voltage", i.e. when it's not charging or discharging. Quick check in the morning, with lights and fans turned off, before solar kicks in. Small solar chargers (even cheap ones), often have volts on display. More convenient than using a multimeter, just make sure that cable from charger to battery is beefy and short, otherwise it will read lower voltage.
Generic table though pretty close. Troian T105 would have 12.1V at 50%.
