And thinking about reducing the weight of the floor panels, i think a splined tin faced roof panel would be very lightweight and very strong.
I'll do some calculations on it and see how it work out. On Tue, Jun 28, 2011 at 9:15 AM, Cody Firestone <[email protected]> wrote: > > > On Mon, Jun 27, 2011 at 9:18 AM, R.
