Where is there a hot in the dometic? We have the 12.5 cu ft model.
Open your access panel(outside?. There will be wires connected to terminals which should have labels. In our case J1-8. J5 is the dc hot. We split the connector and ran a wire through a rocker switch above the frig then up to the fan and mounted inside under the roof vent. The ground can be anywhere. The fan then draws exhaust air up and out. This convection loop then draws cooler air into the space from below. It will take a tester to find the dc terminal in your case.
