2005 Winnebago Minnie Class C Slide maintenance

[Splinterd1]

Hi,
I have a 2005 Winnebago Minnie Class C, I have figured out how to access the rear slide mechanism so I can lube it.
Having trouble finding anything on YouTube as to how to access the front slide A (it's under the sofa/bed on the driver's side)
I'd rather not remove the sofa if I can avoid it.
Any thoughts?

I should add that it is a kwikee digi-sync FLS single rail slide out mechanism
