As far as load path goes I like opt #2

 

thanks for all the input guys. I think i just came up with the best design. i liked the two bars running front to rear of option 3 because they will tie directly into the x behind the cab and the bed bars that will go directley to the rear of the frame. but i liked the weight transfer of the other designs going directly to the windsheild bars. so hears the new/option 4 design. i think this is the best option for strenght when the entire cage and bed is done

 

I like the way it braces all the bends.

 

It'll work fine, but it's heavier than you need
