The cover is held up by metal/wood screws to the frame and wood crosspieces. The cover should be in one piece--if it is in sections, the you can remove the section that covers the slide arms where they disappear into the frame.
Putting it back up is a one-armed paperhanger trick--it ain't easy, but doable.
Be prepared to get a dirt/rust/dead rodent shower when you pull the cover off, and be prepared to pull old insulation out and replace with new--same stuff as for a house.
If you have to cut, start inward from the frame and straightline it parallel to a centerline you have marked to coincide with the slide arm.
The hydraulic piston for the slide is at the rear arm on the door slide; at the front arm for the kitchen slide.
I would make sure I was in a space for at least two weeks due to getting parts--they are standard Lippert parts, but who knows how long to get them?
