Airplanes in a 60' x 60' Hangar?

Anyone have experience with a 60x60 hangar? Our EAA chapter may have the
opportunity to lease one, and the economics will be driven by the number of
aircraft we can store. We'll have a mix of types - figure 25% RV's, 25%
kitfoxes, 25% C-172's, and 25% Cherokees.

Any thoughts on the number of aircraft we can store in that size hangar
assuming the mix of aircraft is roughly as listed?

My guess is that 6 will fit easily, and 8, maybe more, will be possible.

Thanks in advance,
