You would normally only have four wires into the controller, omitting the two for Load, which is not needed in an RV.
Your RV lights etc draw from the battery via the DC fuse panel. the inverter draws directly from the battery in the usual set up.
So your controller is doing what it should. 13.4 is not very high, but could be a "loaded voltage" if the batteries are being drawn down by any loads at the same time, such as the inverter etc. You would usually set 14.8 on the controller for its high voltage.
This time of year the sun is so low, and daytime so short, you might not ever see that , but anything you do get is a help.
You do not need to reset the controller overnight. It will get going again in the morning.
