Hi all. Has anyone installed a jackknife sofa(s) in their ProMaster? I am looking at Lippert industries products and wonder if they can be stored with the seat bottom in a vertical position? I am looking to put a couple across from each other and sleep across the van, but with them in the seat down (normal) position, it would leave a very narrow aisle to get to the bathroom in the back. Thanks in advance for any info, advice, thoughts.
