Can I fit a 90" dining table plus 8 chairs in an 11' ford cargo van?
The dimensions of that table are  3' 9" wide and 7' 8" long. Turn the table top sideways and it will slide right into the van. Stack the chairs on top of each other seat-to-seat beside the table top from front to back. Slide the legs in between the legs of the chairs and it should all fit. You can probably place the chairs any way you like with the table sideways. That van has plenty of room.
