I just got to the hangar and measured too. Not the same as Vic's though, as I came it at almost exactly 9' (a gnats hair less I would guess). But, that's with the normal Van's spinner, so I don't doubt that Vic's right too. He's got the MT spinner. Either way, call it 10' and you could handle any RV-10. The wing leading edge to spinner on mine was about 82" too, but add some additional for longer spinners as well.
If you need other measurements, just shout.
BTW: A rough measurement of wingspan is 31'. Axle to tail tip is 16', Tail width is 12'. These are all *rough*....no snap lines used.
