not sure if you just want to cool the fridge cuz you think it will be too warm or if you want to know how to hook it up to do it out of curiosity- but we have a residential fridge in our Four Winds- we take out what we want from our fridge and start loading up or take it out last and then leave---the fridge runs as you go down the road and they are COLD! at least ours is--I put ice cubes in the freezer in case we wanted a drink down the road--good grief---the ice maker was getting busy and the cubes I brought we solid as ever! The hour or so that your food is in there seems to be no issue because the refrigerator catches up really nicely.......or just wait till first thing in the am...turn on your gen....load up then load the fridge--it doesn't take long!!
