brake lines would work but they are hollow so they would bend pretty easy, probably just a few cartwheels would make it bend, but i dont know, be easy to make fixes though.
what if you took like cage under the chassis also so that way it will keep the chassis strong. im thinking about a cage that fits around the whole truck.
If you could Find some Surplus HYDRAULIC Aircraft tubing, it is Light AND tuff. It is Stainless steel. You can Weld it and also Bend it, but only if you have a Quality Tube Bender.
