Thanks for the heads up! The shell is now getting very close to lifting off. I noticed that the walls directly over the axles will have very little support as there is no floor channel in that area. So I decided to leave two sheets of plywood flooring in place, one each, fore and aft of the axles. This should keep the walls from skating and provide the side-to-side stability you describe.
What I'm thinking about now is the front to back stability. I'll probably use 2x4's on either side, front to back, as some have suggested and double that since I'm spanning roughly 29 ft. and add another 2x4. That would be 4x4 on either side front to back. That should be enough to duplicate the strength of the frame and eliminate any front-to-back flexing. So in sum what I'll have are two ply-wood sheets fore and aft of the axles and 4x4 lumber supporting the walls front to back. That should do it?
By the way I removed the A/C unit today so the shell definitely won't be top heavy. And I covered the hole in the roof with a sheet of plastic flooring from home depot and gorilla tape to prevent any rain damage leaking through the opening.
