How to lube a slide room?

[Hobie16]

I have a 2006 Mckenzie 32SKD (a Holiday Rambler Twin). My question is what is the correct procedure to lubricate the slide tubes? They seem to be fully encased in the underbelly without visible lubrication points. Lately I have been hearing and feeling a chatter and roughness while retracting the main slide room; I assume that a good cleaning and relube will cure this but don't know how.
I am sure someone out there can help.

The tubes enclose the actual working parts. Whatever you decide to lubricate that's exposed to the elements,never use anything oily or greasy. It will attract and hold road grit and dirt, when combined with the greasy lubricant, you just made a crude grinding compound.
Dry-Slide, Moly-lube, and host of other "dry lubricants" are sold for this application.
