There's no more need to lug your heavy generator or totes in and out of your RV at every campsite, hurting your back and taking up valuable interior room; the Bumper-Mounted Cargo Support Arms from Quick Products provide a stable base to hold a generator or cargo container on your RV or camper trailer's bumper! Mounted directly to a 4" or 4.5" continuous-weld square bumper, the set of arms extends out 20", offering the one thing RVers never have enough of . . . more space. The set of arms boasts a 200 lb. cargo weight capacity and may be positioned at a width that best suits your needs. Three angle adjustment options during installation ensure that your support arms provide the most level surface, righting the wrongs of a slanted bumper. The arms are powder-coated black for a clean look that protects against rust and damage. All mounting hardware is included.
