The Dometic 1967 Refrigerator model we found fits so snugly in place it was a tough job to get it in place. After I removed the dividing wall at the entry that has a magazine rack on it, we slid the fridge in. but it would not go quite far enough to allow the wall to be re-installed in its track.
Turns out the 1/4" plywood I had put between the oven and the replacement fridge was the problem. I was surprised that the small amount was enough to throw off the installation.
After I removed the plywood, the Dometic slid in all the way to where the wall could now be set in.
Next I will bolt the fridge down to the floor, and re-install the wall permanently.
Then add back all the trim I removed.
