Can't speak for all RVs but my Toy Hauler and my camping partners RV both charge with solar while the rig is in full use without disconnecting anything, Before solar, when we had generators running and wanted to accelerate charging, we plugged in an external charger and slapped it on the batteries even while the converter we charging at its menial slow rate. Seemed to help speed up charge and did not seem to have hurt anything.
