sofa bed setup in 2008 Montana2980

[captain1]

We recently needed to set up our sofa bed for a guest. I've never used it before and suspect that parts of the bed are missing. The drawer underneath was empty. Does the couch slide out from the wall for setup? Could the missing parts, mattress, inflation parts be behind the couch?

I have a 2008 Montana 3585SA and the couch back pulls forward over the seat. Then you unfold the legs and flip the last section over. Covers up the couch drawer so get what you need first. Mine has a bag that encloses an air mattress with builtin pump. Pay attention to how it unfolds to try and get it back the same way so when you put couch away you can refold it
