I am looking for a desk that will mount in a 2000 Dodge Caravan (Base
Model) that hooks into the attachments for the middle seat.  Also, a
desk that somehow replaces the middle seat without hooking into the
factory attachments is also acceptable if the first cannot be found. 
I am looking for this to facilitate a mobile office situation with a
laptop and printer mounted to the desk.  I would like to be able to
sit in the 3rd row seating while using the laptop mounted to the desk.
 I have seen many mobile solutions including "airdesk" which seems to
the most prevalent on the web.  These "airdesk" type desks will not
work for me because they mount in the front of the vehicle and do not
have any working space, only room for the laptop.  I need to know
where to buy these desks for a reasonable price <ie: $1000 and under>.
