Penny and I have spent the first year with our 2604WS getting "Rocky" personalized. Penny is a quilter and fabric artist so the factory interior decor had to be ... (how shall I put it?) ... "colorized." Many of our mods involved finding bright fabrics to brighten and add interest to our brown interior.
I found simple, easy (and cheap) solutions to many problems we had concerning storage and adapting to life with cats. Some of these mods are specific to the 2604WS and others are not. Some are so simple as to not be rightly called "mods." (One involves the placement of a document clip)

I hope one or two will be of use to someone else.
