2017 Thor Chateau 22B with Queen Slide Out

I watched the short video

Pretty good. Three questions:

The guy says "Lube it from the inside as well". Is that what you do? Do you do it with the slide open or closed or half way? How do you get the trim around the bed off?

How often do you lube it?

What about the rollers that bear the slide out wait, no lube?

As with everything RV there are tricks and tips, anybody have any?

Thanks
