Anyway I now think the problem is with the trailer and will test it when I get home and have more tools and time.
ALL of the voltages you report look perfectly normal.
You may need to contact a truck dealer to see what they know.
With the number and type of batteries that you have you might just have to live with that occasional indication.
Most all electrical systems that include a battery expect to HAVE a battery there....all the time. Voltages measured without a battery in the circuit can be deceiving unless you have some engineering spec's to tell you what to expect.
