Erez I am trying to get a box measurements and then concentrate on where it should be wider, narrow, taller, shorter etc etc.

Volume - 600kg
Length - 5.0m
Width - .35m
Height - ????.45m .46m .44m????

After we get this box dimensions, we can play with placement of the values. For instance how far back will the tallest, widest thickest point be? Rocker placement, crossbeam positions and everything else.
