Thanks, we are happy with the way it came out.
Here are a couple of details on how I secured the refrigerator.
I used 3 framing angles, one secured through the floor, one to secured to the wall (right side of the second picture) and one to secure to the ceiling.
This bracket is a rafter tie screwed to the ceiling, an angle screwed to the top of the refrigerator and they are tied together with a straight strap that I drilled a few hole through for bolts.
Probably less then $10 in parts to secure the whole thing and it doesn't budge.
