Hi Guys - I figured I'd try something a little different.  I purchased two of these AC ammeters (one for each leg) because it provides Voltage and Amps in one meter:

My thought is to also install two of these DC power meters, one for the Engine batteries and one for the House batteries:

Once I received the DC meters I realized the 100 amp shunt may not be big enough.  There is a 300 amp version as well.  

Does anyone know how many 12v DC amps are pulled from either battery banks and/or what size shunt I should get?  Or maybe the first question should be - Is this a bad idea?  

My idea is to install the AC and the DC power meters over the front entry door.  I have a small CNC machine at home to cut the black polycarbonate panel to the correct shape (pic below), including the terrestrial antenna controller.  By doing all of this, it will open up the space over the driver to place a proper sized bookshelf speakers on either side of the TV (I like to listen to music).  The receiver/amp will be hidden behind the TV.
