Our all-new RevX design is great for cargo, and great for hauling your Honda, Champion, and Generac generators. Mount Your Power Near Your Plug and stop lugging your heavy generator from truck to trailer and back! Our RevX tray kit design features over 60 independent tie-down points around the perimeter of the tray, the most available on any tray. The RevX also is the first to feature 8 tie-down points in the center of the tray, allowing you to more effectively secure smaller generators and cargo! Our beautiful GennyGo cargo carrier tray kits mount directly to your standard 4-inch RV bumper and are available in either sanded-finish aluminum, black powder-coated galvanized steel, or a combination (Hybrid). Tray pans are 24 inches x 24 inches inside of fence to inside of fence; the platform area can be expanded to 24 inches x 29 inches using the included “Extended Assembly” and utilizing the bumper’s top face. Weights (in pounds) and capacities (in pound-feet) for the GennyGo RevX tray kits are as follows: Standard (2-Arm) Kits: Aluminum: 12/125, Hybrid: 16/200, Steel: 24/200. Heavy Duty (4-Arm) Kits: Aluminum: 16/250, Hybrid: 24/400, Steel: 32/400. Pound-feet = weight (in pounds) x distance (in feet) from bumper to center of cargo weight. All mounting hardware and parts are included. Our unique, patent pending design gives you 3 different assembly options included in each kit. Build up to an 8 foot-wide platform by adding more trays.
