Easy from roof end but at the bottom the fridge sits on a wooden platform which is above, say, where the power centre is that includes the converter and fuse panels.
You take off the vent cover on the side of the RV which is at the bottom end of the roof vent, and drill a hole in that wooden platform--BUT FIRST--check below that to see where you are going to drill a hole will not drill into something important like your converter
๐So now you have your wires into the compartment under the fridge and you can go from there. Or you might be able to go sideways into another cabinet beside the fridge but there is almost no room at the sides at the back of the fridge.
