According to Lippert (builder of slide mechanisms currently used by Forest River) only place on slides, at least through frame electric or hydraulic, that get lubed are the side plates on the gear clusters where shaft goes through them. Use a DRY Silicone spray.
They EMPHASIZE not to lube the actual gear, polymer wheels (that actually support slide rails), and rack gear teeth.
Check out their online slide service manuals.
