What unit am I needing to replace what I have so I keep the same capacity charger and pass thru capability? The price difference indicates there must be a difference. I have shopped and just want to purchase the correct unit.

a call to magnum will get you all the info. they are very helpful and normally walk you extra miles to get your issues resolved.
since your coach is pretty new, i would recommend a 3012 or 2812 inverter. price wise not too much difference between them. you don't need to change anything but just the inverter and the remote. i replaced my zantrex freedom 20d with a ms2812, diy, couldn't be happier.
