I was talking to a friend today who said he saw an RV-6 or 7 at Oshkosh with two seats facing rear in the baggage compartment. The rear panel was moved back to allow more leg room and the owner claimed he could carry 4 adults with no weight issues. Has anyone else seen or heard about this? Is it legal to do this? The plane was a tail dragger. The pilot flew it into Oshkosh with 4 people on board.
