Basic idea is yes, but the devil is often in the details!
Is the coach battery disconnect left on?

If that is off it will disconnect the batteries from the charge as well as many, but not all the drains on the batteries.
Safety item are often still powered ,even when the disconnect is showing them turned off

Uh, I'm not sure how I can disconnect my 2 coach. batts.. have bot see that button.... it appears that both the solar panels n 120 30A are charging the Batts..... which means there's a 120 to 12vdc converter in this era70x....

Side Q, I was listening to the radio for few days with the power switched to coach batt n I noticed the chassis batt going to " orange level" on volt meter.... which Didn't make sense , as I thought the chassis batt should be completely disconnected from drain at this point.... ?!!?

Yes, it does often take some back and forth questions to get down to the real answers!
I like to drill down to what is real on the specific RV as there are so many and even in the same year there are changes made.
So a point to ask about before searching out the drawings, involves the serial number of your RV. Winnebago uses the 7th digit of the serial number (not VIN!) to tell us which build we have. A 1 in that 7th place is an early year or 2 is a later build of the same year.
The problem is often that those changes are in the electrical items as that field is changing so fast! If you can check a label at the driver's side or near there, it should have the serial number or you may have it on paperwork?
With that info we can go to drawings and be more sure we are looking at the correct info!

When you put the radio on "coach" you are bypassing the need to use a key in the ignition to listen to the radio - but you are using the house battery to power the radio. T

The coach or "house" batteries have a disconnect switch.

I'm not at all clear on what you are saying with the solar panel and converter part of your first sentence. Yes, you have a converter, which charges the house batteries when you are on shore/gen power (only). Solar panels are separate of the cutoffs and just connect directly to the house batteries from the solar charge controller.

Your Operator's Manual details some of this info. Here are some screen shots of your manual Section 6 Electrical:
