Corrected now.
What would you expect to happen?
With no shore power you are reading the direct chassis battery voltage.
If you have a single battery disconnect wired in your coach it has nothing to do with the chassis battery, only the house batteries.
When you plug into shore power the converter applies charging voltage to the DC buss.
In most class A RVs there is a BIM/BIRD, etc that allows charging voltage applied to one battery set (your house batteries in this case) to also be applied to the other battery(s), your chassis battery in this case. So the 14.2 VDC you see applied to the chassis battery when plugged into shore power is coming from your converter.
In some coaches this cross-connect is from battery set to battery set: this allows the Alternator to charge the house batteries even if the battery diconnect is open.
On other coaches this cross-connect is from the house DC buss to the chassis battery: this allows the converter to always charge the chassis battery.

It should have been
House batteries. I had typo when I typed "I have Digital LED Readout in 12vDC socket in Cabin, it runs off the Chassis batteries. " I only have one chassis battery.
I will stop draining my batteries and send some pictures of what I found. I have multiple 12vDC outlets throughout the coach and they all have same reading from house batteries. If I turn the house battery switch (or house Battery disconnect switch) to off, they all go dead. I know this for fact as once I was driving on highway and I noticed my radio wouldn't come on and my phone plugged into that socket was rapidly discharging trying to run the Waze apps. After about 20 minutes I pulled over and saw where I accidentally turned off the house battery switch (no green LED)
I appreciate your digging into this to try to help me. Be advised that what I send is not to prove anything but to honor your request. I just know that after a year or so of reading dos and don'ts on the Thor Use/Store switch, I don't think I am getting the same experience with this model of Winnebago. i.e If shorepower is on, I cannot turn the disconnect switch to Off. In turn I believe my batteries House and Chassis batteries are always charging if I have shore power. If not I sure can't use the disconnect switch to turn green LED off to black as long as I have AC.
Pictures to follow.
