We currently own a 2008 Expanda 12-37 in very good condition. We are considering selling and upgrading to a larger van however it appears that the 12-37ft vans are rare and I'm unable to find any currently for sale which would provide me a guide to their worth. Does $14-15k seem reasonable for these vans in today's market? A couple of pics of the van are attached. Any feedback would be appreciated. Thanking you in advance, Regards Bryan
