The HC1500 is a line of Hydrogen-powered civilian transport manufactured by HuCiv. At least two different variants of the HC1500 are known, one with four tires and a cargo compartment in the back and another, heavier, six-wheeled model which serves as a tractor unit. Both models were used by Traxus Heavy Industries on Reach.
About this creation
Pretty much I made a minifig size of the Halo Reach truck in the campaign you can drive.
