I forgot to add: If you purchase this rack, and I highly recommend it, be sure to limit your door travel to about 90 degrees. This isn't optional. Winnebago uses 1/16" braided steel cable and proprietary clips and they don't last. 1" nylon strap works better and lasts longer. Fold it over at the end, punch a hole in it and find a bolt somewhere on the door hinge to attach it to at both ends. Inspect it frequently.
Also, when I'm not using the rack I remove the wheel holders and clamp arms and stow them away.
