The bodies of our disaster recovery vehicle are manufactured utilizing an all aluminum aircraft grade 5052-T6 alloy construction to insure long-term durability, corrosion resistance and strength. The frame of our disaster recovery vehicle bodies are manufactured using aluminum tube sections except for the floor section which are beams. All structural tubing on these disaster recovery vehicle bodies are welded together utilizing aluminum extrusions at the roofline and the corners. As aluminum extrusion adds great strength and durability. The outer skin for the body is a 0.125 inch aluminum sheet for maximum strength and resistance to damage from normal use. We have 17 years average employee experience designing and building these disaster recovery vehicle structures.
