All conversion parts are now US sourced. Roof, cabinets, seat/bed etc.
Main differences are:
No more track system in floor thus rear seat is fixed, adds approx 1 in. to vertical space.
New popup roof design but still in familiar v-form, upper bed folds rearward rather than single piece that attaches to roof.
Swivel mount is standard for pass. seat optional for driver seat
It's unclear if a table will be set for a floor mount or on a turning arm mount.
There is probably other items I am forgetting but you should check out the pix at gtrv.com and the video on the facebook page or via twitter.
