oh yeah it will be braced, also doing it in the rear corner on drivers side so the factory braces will still be there, and it will be braced to the frame underneath like a fuel tank to a frame (big rectangle tanks on the side of truck frames)
since this area is past the suspension points and such floor flex/twist shouldn't be an issue (also that area of the frame also has a "roll cage" for support and protection of the fuel tank)
also plan is to not really support it with the bus floor
I still have to get underneath and measure etc...in my head it'll work...
also a sunroof bubble is still a possibility also...so maybe won't go thru the floor.
we'll just have to see
