After much suggestions and helpful comments this has taken a new direction more towards a buggy. Inspired by TF and other designs. I have dropped the full cab and went to a hatch back design. It is lighter, stronger, lower and more stable. It uses coil overs instead of the crazy hydro/air combo. I need to work with auto desk inventor once I get back to the house around thanksgiving plugging in the numbers and seeing about issues with clearance and figuring out the spring rates for the coil overs. I have a lot of it figured out "close". But, it sure would help to have all the geometry figured out a few times over. I should have every bolt and weld planned and checked over by February and be able to start welding and playing with this by March hope fully.
Here is a sneak peak of the rough design.
