SHobbs,
Here are some pics for you...
Here is the rear of the unit with the access panel removed:

Here is the lag bolt detail. I used a spacer between the floor and the bottom of the unit to keep from deforming the bottom panel. This keeps the lag bolt from coming loose:

Here is the Piece of angle aluminum trim at the top. I used a piece of long angle in case the fridge decides to rock back and forth in the hole. The 2 lag bolts and this piece actually hold the fridge in the hole. I overexposed the all the photos a little so you can see the screws and other things:

Here is the top with the door closed:

Here is the bottom piece of straight straight aluminum:

Some other things... I made the fridge a VERY tight fit. There is only about 1/16" between the sides of the fridge and the wood on the sides. I used black electrical tape to trim the sides since the gap was so small. The flat black tape matches the fridge and trim perfectly. I also used carefully cut "Swim Noodles" for insulating the gap behind the trim on the top and bottom. This Magic Chef fridge has about 2 to 3 inches of clearance on the sides (inside the opening), 2 inches of clearance on the bottom, 2 to 3 inches of clearance to the rear and about 1 foot above in this particular unit (Travel Supreme). I forget the exact measurements. But it is plenty of room and the unit never gets hot.
Luckily all the wood work inside our camper is solid maple and is very difficult to damage. The old fridge leaked pretty bad as it was on its last leg. So, there is a little water damage on the cabinetry beneath the new fridge. If not for this one little problem, the unit actually looks like it came this way.
Regards,
AJ
