From time to time a couple of storage questions have arisen on this forum concerning shoe storage. The 2604WS (as well as its sister 2608WS) has plenty of clothes storage but a place to put shoes is a challenge.
I found a neutral, fabric shoe rack and cut it up to fit in several places.
Here's Penny's shoe holder hanging in the wardrobe:
I also put one of these on each side of the bed.
Storing the sink covers when we're using the sinks was also a problem. Solved by converting the furnace air return panel into a true door. This is used only while parked and doesn't interfere with the return.
I hate wasted space so opening this door put a frin on my face.
