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 in. or 4.5 in. continuous-weld square bumper, the set of arms extends out 20 in., offering the 1 thing RVers never have enough of more space. The set of arms boasts a 200 lbs. cargo weight capacity and may be positioned at a width that best suits your needs. 3 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 prevents rust and corrosion. All mounting hardware is included.
