That hummer also weighs in excess of 5000 pounds stock not including the missile system and is designed to have recoil less rockets fired from a top mounted turret. That Toyota truck weighs less, has a weaker chassis, and is in no way designed to have a non professional weld job mounted missile launcher designed for a hind gunship mounted in the bed. The Toyota truck only weighs about 3000 pounds, firing that system on the slightest of inclines would literally roll the truck over.
