I checked our sales receipt and we have an Isotherm Cruise 130 ASU Refrigeratror with freezer compartment, 12/24v DC only, Part No. 1130EE1AA0000:
The "proud" descriptor refers to the door sticking out past the cabinet...compare the drawing of the unit with the "proud" flange with one on the link from the above url. I would not want the proud feature since it would just get in the way. Look at the photos of my complete installation and you can see that the front of the unit is flush with the counter above it.
Our frig has the hinge on the left. In our EB-50 floor plan, my wife can open the frig while I drive and retreive a bottle of water from the door storage which is very handy. When we load it, the door will swing completely open...if the hinge was on the right, I think that the open door would hit the turned around passenger seat.
Let me know if there are other questions...
