Hopefully if there are enough of us expressing interest... maybe this will be the next RV. I, and others have posted this before. While I realize that most of the time we only fly with 1 or 2 - and for most of the RVers out there this is fine. However, for me, there are times when I need a back seat. Or how many times do you wish you had a bit more baggage room? How many threads have there been on this or other websites addressing squeezing in folding bikes?

I've heard the argument that you can rent a spam can for those other flights. But frankly - my options for rentals are a couple of very tired C-172's. Having something better than a spam-can is why RV's are built.
Currently the only option for those that want a little more room than a 7/9 is an RV10. It is reportedly a wonderful plane - but building it and obtaining an O-540 is frankly quite a bit more expensive than the 7/9 series.
I think there is a market for a "Stretch-9". A "2+2". Something smaller than an RV-10. O-360 powered with either a slider or tilt-up canopy.
