That’s an actual SMB Classic. Cutaway chassis with the wider composite box. Extremely rare - only 8 existed as of 4/25/21 per this thread:

The waiting list is like 4 miles long. Wouldn’t be surprised if they get that price.
Just realized these SMB Classics with the fiberglass rear section do not have any gutters down the sides and only a length of ?? over the rear doors to divert rain.
