I removed a jack knife couch from our Bay Star. It wasn't that difficult. By lifting off the kick plate, I was able to remove the lag screws that attached it to the floor. Then, it was possible to move it out from the wall. If I remember correctly (???), I released a couple of springs and then I was able to separate the back of the couch from the seat. Then it was fairly easy to take the two sections out. Then I put the couch back together and was able to sell it cheaply to a young guy that was redoing a trailer.
If all else fails....using a reciprocating saw will pretty much guarantee you that you can get it taken apart!
Retired but busier than ever!
