Wardrobe dimensions

I can't help with specific dimensions as my pod is also stored for the winter. However, I can offer some suggestions and pictures as to the way that we added shelves to our 179.

I used standard 12" wire shelving available  at Lowe's/Home Depot. I cut each piece to the proper length in order to fit front to back.  I added a piece of wood ripped from a 2x4 that was the correct width to make up the difference in width side to side-as I recall, it was somewhere around 1" difference-make it a tight fit.  I stapeled this wood piece to the edge of the wire shelves using many heavy duty staples through the wire edge. There are solid 3/4"x3/4" supports in each corner of the wardrobe cabinet.  I screwed into these corners to support the shelves. I made "pegs" from used 1/4" copper tubing as a hollow peg and used a long screw through the copper tubing to support each corner of the shelves. The shelves sit on the tubing/screw posts in each corner. Here are some pictures

I hope this helps
