Luckily where I work, I have access to the equipment to build this. Just have to weld it together in the boxing areas

Oh boy. Clean sheet design opportunity 
There is a lot to gain by using a larger section frame rail, both taller and wider. Same goes for X members. Wall thickness is important for strength but is not as effective as section size for stiffness.
Section bending stiffness goes up by the fourth power of the dimension so if you had a 7.5" tall rail instead of 6" the bending stiffness would double. Here's a cool little calculator if you want to play with various sections.

And a massive X member.

I have no idea to be honest. I had a guy at my work do it up. Hopefully does the metal work soon so I can progress.
