Greetings Twells,
The 22M uses the Lippert SlimRack. It is a floating rack with a captivated pinion which eliminates the tight ¼" tolerance on the slide-out box required for the sidewall-mounted rack types. It is very robust and fairly maintenance-free.

Hi Twells,
After over 4½ years, I still absolutely love it! I have had very few problems with it, which I attribute to the "old ways" of building a Winnebago. Yes, it is boxy, but it works so well.
