Stan, Looks similar to ours once I put in the new floor. No more drawers, but heater register and CO detector still there. I should have said rails, not stiles are joined with pocket screws. Like your photo shows, Beaver put in stiffing webs (vertical ply braces) mid-depth on both cabinet walls, nice touch. I covered both with some split foam pipe insulation. Our fridge fit between the braces with just a bit of clearance. I had to re locate the fridge and Ice maker 120v receptacles, re locate and replace the ice maker water line, remove and cap off the Propane copper tubing and put in a pipe plug in the gas pipe behind the cover in the lower compartment. I removed the rail and the top of the fridge cabinet and made a new one giving me an inch or so clearance at the top of the fridge. Then I worked on making the fridge access door insulated and (hopefully) air tight.
