If I wanted to run a fridge while on the highway and not on propane, I would mount an inverter under the hood close to the battery, then run a 110 volt cord back to the fridge circuit.
Or you could plug the whole camper into it and the built-in charger in the camper would keep the camper batteries up.
Having the inverter in the camper is far more logical, then you hook it up to the house battery bank, not the engine start battery.
DC to DC Charger takes car of the charging needs while driving, rather than dealing with inefficiencies of inverter doing DC to AC (with underhood mounted inverter) and then the DC charger in camper converting the AC back to DC.
