Determining True Capacity of Trailer When Title and Coupler List Different Limits
Question:
Hello, I have an 18foot tandem axle trailer that has a title, certificate, and registration all stating the GVWR is 7,000 pounds. However, the a-frame coupler that is welded on from the factory is stamped with a maximum capacity of 5,000 lbs, and a 500 lb tongue weight. Why would the manufacturer put a 5,000 lb. coupler on a trailer certified as having a 7,000 lb. GVWR? I am confused if I am limited to 5,000 lbs. max or the 7,000 lbs. the trailer is rated for.

A trailer is always going to be limited by its weakest component. This means that even if everything else on the trailer (axle, hubs, wheels, suspension, etc) is rated for 7,000 pounds, you will still need to adhere to the 5,000 pound limit on the coupler.
I'm not really sure why a trailer manufacturer would install a lower rated coupler on a trailer. It's also possible that it wasn't the manufacturer but a previous owner who needed to replace the coupler and simply didn't pay close enough attention to its weight rating.
We do have a nice selection of 7,000 pound A-Frame couplers available, such as the etrailer.com # CA-5196-B that you can take a look at. This particular coupler features a hinged ball socket and pin fastener to ensure a secure connection and is compatible with 2 inch hitch balls. I have attached a short video demonstration on this coupler, along with a couple of links that will take you to our selection of 7,000 and 8,000 pound couplers that you can look through.
Replacing the coupler with a 7,000 pound (or higher) unit is your only option to get the trailer back up to the 7,000 pound GVWR that is listed in your paperwork.
