This mod using the base from discount van is common. The below link discusses it on both the E350 and 450 chassis and yes it swivels the full 180 degrees. https://groups.yahoo.com/neo/groups/...ns/topics/7214
talks about several that have done it. Most also change the console on the doghouse to a smaller one (mine has the smaller one already installed) to make the swivel easier. I intend to add this mod soon. The dinette in my rig has a piano hinge on the back next to the passenger seat so I can flip it down if I want the added room. Both the flexsteel and standard Ford seat will swivel. I can send a copy of the PDF of a member doing it in a 2005 Glacier (Chinook Class C) if you send me a private message. Folks have done it in the Class B (Concourse) that I own as well.
The catch? Most recommend against doing the swivel on the driver's seat. (The link details why)
