As I have previously stated on this forum, I had a expansion fridge that came with my 2012 RoadTrek 190. I changed it out to a Nova Kool R4500AC/DC model and it was, by far, the most successful mod on the RV. It runs on AC shore power, but has an internal inverter that allows it to run on DC. Wherever I am, on whatever power available, and whatever the outside temp, hot or cold, it can keep a 36 degree refrig and 0 degree ice maker. I would never go back.
By the way, it can also go 3 days on coach batteries, if other electrical services are carefully monitored. Good mod.
