I bought the first two from a different supplier who has slightly newer
stock. Commercial Products, division of Truck Fridge, is where everyone else
is buying, that's where I found the stock of 200+ units that I was able to
set up the group price on. So that's why the difference. Mine does have a
fan on the condenser also, maybe not visible in my photos. The AC add-on box
was also different on some, as it was added on to make the DC + AC version,
when the stock fridges were set up as 12/24 DC. The new Truckfridge is
basically a licensed copy from what I understand and they are able to sell
them for less because they aren't being made in Italy. Still lovin' mine, so
much that I got the SS 90-liter version for my highroof project. :-)
