My and my wife's favorite improvement is removing the closet bar that ran the width of the trailer, sawing it into three smaller pieces (with a little bit left over), and mounting these three smaller pieces 90 degrees from the original orientation. This works very well, and my frustrations with clothes being caught in the door, and being scrunched up have been solved. I used the original hardware for two of the rods, and fabricated two more out of wood for the middle rod. I used little plastic covers from WalMart to dress up the ends of the rods. While there is a little less total space for hanging clothes, what we do have is easy to use.
I tried to upload some pictures, but don't know if I did it right.
