Trailer coupler rating
Hello, I have a 12' x 8' flat bed trailer with brakes that weighs 1200lbs. It has a 5000lbs rated coupler on it with a 2" ball. The trailer is rated at 7000lbs and I plan on carrying 4000lbs of stove pellets on it a few times a year. This puts it over the coupler rating as well as the reciever drop hitch I have on my truck by 200lbs. The trailer hitch I have on the truck is a class 4 so I'm OK there. The question I have is, why does a trailer manufacturer put lower rated couplers on their trailer when they are rated for much more or, is this Ok to use?
Thanks for any help, Scott
