I have an excellent condition Sofa Bed Seat out of a E-350 Sportsmobile with 11,000 miles on it. the original owner did a very weird layout and had the sofa bed toward the front of the vehicle instead of the usual RB-50 layout. Below is a link to the Craigslist ad.
Let me know if you have any questions or want more pictures. I'm looking to get $500 because the new gaucho cost me about $1400
