Trailer Identification

First off, no pictures unfortunately, so no point in asking. I tried searching on here, but couldn't find anything related to IDing the different trailers. Quite a few years ago, a friend gave us a trailer to tow behind the Jeep on camping/hunting trips. It has the same angular fenders as pictured here:



However, the sides of the trailer are straight, there are no angles at the top like on all of the trailers I've seen. It's probably just something that someone put together since it's sitting on a (broken) Dodge truck axle, but I just wondered if anyone else has ever seen a Jeep trailer with flat sides and angular fenders.
