Dutch Air 120V Fridge Cooling unit (Vent Modification)

The space issue for the compressor is specific to the fridge (in my case a Dometic 1292) and how it was installed in the RV (in my case a Mandalay 40D.
Other fridge makes and models don't have the issue, as well as other RV's. My friend just installed the 12v version in his Tiffin on a Norcold and there is no space issue. But JC's can and did tell me how much space is required behind the fridge for the compressor.
