I’ve seen a a few members with Dissent rear bumpers tow their boats, campers, and trailers that definitely weigh more than what you have and they don’t seem to have any issues at all. Don’t remember exactly who but maybe they’ll catch this thread and chime in. Most aftermarket rear bumpers that are manufactured by smaller companies don’t rate their bumpers for several reasons, one of which being the high cost and time associated with the process of having it DOT rated. It’s extremely expensive to send multiple bumpers to the NHTSA (National Highway Traffic Safety Administration) which are then crash and load tested until their breaking point. Not to mention the liability involved if someone God-forbid had an accident while towing and their cargo or vehicle passengers are injured or killed; that blame could fall on the manufacturer and be devastating. That’s why you see a lot of aftermarket bumpers both front and rear labeled as “off-road use only”.
