Thanks for the help.
In the Axis, your converter/charger (if it is working correctly- a big if) has three stages. If the batteries (either the coach or chassis) are below 50% charged, the charger puts it about 14.1v until all the batteries are above 50%. Then the charger drops down to about 13.6v until all the batteries are are fully charged when it drops down to about 13.1v - maintenance charge. This is to keep the batteries fully charged and not boil and ruin your batteries. Unfortunately, the converter/charger in the Axis (WFCO) is not the best. I have had two in my 2014 Vegas and Axis and neither worked as they should. One would not go into boost mode and the second would not go into maintenance mode - which can quickly ruin your batteries. I replaced the one in my Axis with a Progressive Dynamics and it works as it should.
