Apparently Electrolux fridges became Dometic, so essentially they are the same fridge.
The way to tell is to look at the front of the fridge:- on the new Dometic RM122 the flue is on the right hand side. This is per O'Briens camping web site.
All the above is basically spot-on , however the Domestic is much improved .
Internally the Domestic has an oblong cooling element at the back of the fridge and one piece plastic coated white wire shelves whereas the Electrolux has an shelf type element on the right and 2 piece dark brown plastic shelves .
Best way as kev H says , is to look which side the flue is on .
I`d say a Domestic is worth twice as much as an older Electrolux - basically the same but much newer ..
