I blocked the side door access with 1 inch foam board rigged so that I can remove the foam board to get to back of refrigerator. It is not "air tight" but does block a lot of the air movement. I completely sealed the roof vent. Refrigerator is bolted to floor in rear with through bolts/nuts/washers.
Mine has furnace below the refrigerator platform, so I drilled some air holes in the refrigerator platform. When operating, I get a good flow of air out of the small gap above the refrigerator and it cools good even in hot weather.
Velcro straps top and bottom with tabs on doors keep the doors closed when traveling. Additional tabs on cabinet so I can push the strap into the cabinet when parked and keep the velcro strap out of sight.
I love the additional space inside the refrigerator.
