New Solar Setup - What am I missing?
Put in 4 new 6v Interstate batteries and added another 100 watt panel and a controller. Getting ready for some light dry camping. Background - I have no info on the original solar panel. I knew it ...

The 12V bus going through the camper should be connected directly to the battery (via a fuse or breaker, and possibly a cutoff switch), so it shouldn't be at a voltage different than the battery.
Switch to the new setup with a second panel and a controller with the old panel connected on the roof. The controller says under no load there is 16.9 v on the DC bus...The actual battery voltage is 13.4-13.8 if the coach is sitting in the sun.
