Down fridge vent or not - it depends. If you wire panels in parallel (recommended if there is any shading), then you need a junction box with a short run of MC4 to the box, and then #6 or #4 from the box. This box would have to be either on the roof, with #6 going through the bottom of the box into the roof, or on the fridge vent side - AM Solar have such a box. Looks a bit ugly when you put vent cover on, 'cause it doesn't fit well under the cover, but it works. On the List of installs you will find both methods: with the rooftop box from Home Depot (be Renoman, if I'm correct) and with the AM Solar box mounted on the fridge vent (by Sleepy).
With panels in series up to 600-700W you can go with #10 MC4 extension through fridge vent or plumbing vent, junction box is not needed so you can avoid extra hole in the roof.
With residential fridge you need 400-500W solar to feed fridge alone, on a sunny day. If you plan to avoid using a generator as much as possible (wouldn't make sense carrying all those panels otherwise), you should either stay with LP fridge, or consider 5-7 cu.ft 12V fridge.
