question for the solar gurus
Trailer is stored and not being used at present. The solar system is active and keeping the batteries charged up. Every morning it goes into 14.4 volts absorb and later 13.7 float. The batteri...

You're charge controller is doing exactly as it should.
It will charge at 14.4 until it sees the current flow drop to a minimum amount and then work it's way to float.

Depends on the controller's charging profile. The standard profile for EP Solar ones is to raise the battery voltage to 14.x (where x has three choices for Wet, AGM, Gel) and then hold it there for a fixed two- hour time and then drop to Float.
Others with one settable voltage will go that setting and stay there all day till night allows the battery voltage to go back down.
Some go to 14.x and then drop to 13.x right away. Some of those have adjustable settings for the two voltages, so you could lower the first one to float and it will "drop" to the same voltage, or if you want time at the higher voltage you can set the float voltage up to near the absorption voltage.
Some fancier controllers will have an adjustable time to stay at Vabs before dropping to float.
