Hi 1575'ers,  though we are new to this forum, I have found a wonderful closet organizer.  It may be helpful to other Lance owners too, but this one particularly fits the 1575 closet perfectly, scooting inside behind the little electrical chase and filling the space with just about an inch to spare.  It hangs off the coat hanger bar so it is an instant installation and can hold up to 60lbs, (the shelves are stiff plastic I believe), according to the item description.  The sixth cubbie is squished, so basically unusable, but the overall size makes the best use for what we wanted.  We are just rolling our clothes and other things like kitchen towels and placing in the cubbies.  For longer trips where more clothes are needed, we can put them in a cupboard under the dinette.
