Hollywood’s TRS (for Tire Retention System) Rack offers everything needed in a hitch platform rack at the nice price of $329.99. It’s made to last, with a sturdy steel frame and aluminum wheel trays. It mounts to both standard vehicle hitch sizes. And it has a super secure attachment that locks it into the hitch so it stays tight and doesn’t sway. Hollywood also invented the ingenious Rack Valet, a mobile bike rack storage and transportation system for most hitch racks (not just Hollywood's).
