We just brought home our new 2015 Elkridge 37 Ultimate last night and we are in love!! We were able to turn the living room sofa into the bed, but can't make the bunkhouse sofa turn into a bed...it looks like they should both work the same way (neither has a blow up mattress), but wanted to see if we were missing something and they really are different. Thanks for any help you can provide--I didn't see a manual on how to work it
