Cargo load platform assemblies are especially adapted to provide support for a variety of cargo, such as auxiliary aircraft fuel tanks. According to certain embodiments herein, a load platform is provided which is adapted to being positioned onto a cargo deck of a cargo aircraft. At least one anti-rattle device is operatively associated with the load platform for positionally fixing the load platform to a tie-down ring of the cargo deck of a cargo aircraft. The cargo load platform may support a rigid fuel tank thereon so that auxiliary fuel tankage systems can be provided as may be needed.
