The 1+1 seat is what I have for the REV. A bracket is located in the trunk for the seat to mount to. When the two up option is not used, pull the seat off, put the trunk on and it is a one person sled. If you want to bring a passenger, remove trunk lid, snap seat into place and it's all good. Neighbor had one and sold it for $350 shipped to the east coast some place.
