Sounds like a great project, Mike! I wish I had some insight to your DMV issues. The converted furniture/moving van was a very popular upgrade from the ramp-truck, and I remember seeing a lot of them on the East Coast in the late 60's and early 70's. Lou Olynick did quite a few conversions, most notably for Bill Jenkins' Pro-Stock Vega, with beautiful parquet wood flooring. That truck is still around the NJ/PA area, showing up at the York Reunion in 2010.
Not sure if you've seen this thread, but a lot of good ideas here -

Good luck!
