Followup: Well, with no replies (but lots of views) to my question I decided to use " best judgement" and mounted the outlet ( a shallow 110v rect box) above the fridge
in the vent chamber on the left side looking at it from the outside...there's so little room once the fridge
is in place that the cord will need to be plugged in during/before frig installation (maybe that's the reason for the long cord length) . This keeps the cord from needing to travel out of the venting chamber, which as we know, should be sealed so carbon monoxide doesn't infiltrate to the inside of the trailer when running on propane
p.s. just a word to the wise now that I think of it...the venting of the fridge
on these Jubilee's is done by the wooden "cabinet" walls on the sides and bottom, but on the top it's a piece of light
gauge steel sheet caulking sealed to the frp exterior wall (above the top grill), to top of the fridge and to the cabinet sides. This steel was rusted completely out on my original cabinet and would have been a "death trap" if it wasn't replaced...problem is, it's almost impossible to get a look at without removing the fridge and even then you'd likely need a mirror to really look it over. My replacement is of heavier gauge aluminum. Unfortunately this replacement would be very difficult without moving/removing the cabinet.
owners/ purchasers, take note!
