In other words, since the solar is normally outputting power in daylight, it will put out power both when traveling and when set up for camping. Do I need to be concerned about overcharging?

The solar charging system uses a controller that when properly set up will not overcharge a regular battery. If you are plugged into shore power the converter and solar system will provide power to the battery and the battery won't care which source it's feeding from. When the full charge voltage is reached each will switch to the Float mode and life is good.
If you have Lithium batteries that don't like to sit a long time on Float, make sure you have a way shut off the output from the solar panels, preferably a switch.
From what I understand solar controllers don't like to be disconnected from batteries while the panels are producing electricity.
Give babcock a shout out as he's far more knowledgeable on that than I.
