One of the challenges of being a new Keystone owner is adapting all the empty storage spaces into usable ones. We quickly approached the pantry in the kitchen as our first task. How to transform this area with deep trapazoidal shaped spaces into something efficient was the challenge. So we began by measuring all 4 sides inside. Then we built shelves using 3/8 in. baltic birch (easy to stain). In the tall center area we went one step beyond and built a sliding drawer using Rockler wood cabinet glides under it to provide stable, accessible storage for canned goods. For each shelf support we attached 1/2×3/4 in. wood strips through the thin side walls using small decorative bronze screws from Home Depot. The Bronze color matches all the other hardware in our unit so is not noticable. On the inside of the right hand doors we built small 6 in. wide boxes with slatted fronts to hold all the boxes of ziplock bags, foil, and plastic wrap that RVers use. Couldn’t do the left side as Keystone’s design for decorative trim on the slide prevents the doors from fully opening with the kitchen slide open. Another aw shucks moment!
