I just don't get why people chop these trailers up. It's cheaper and easier just to adapt your hitch, change the bulbs and wire up a light plug adaptor.
I have used these, and they are not very practical without a tailgate.
Remember most people do not ford rivers on a regular basis, and don't need a water-tight trailer.
There was a time when the receiver hitch did not rule the world, and pickups had sturdy rear bumpers with holes for a towing ball, and no holes for a pintle.
Also if your other trailers used a ball hitch, why spend the money for a pintle hitch and the receiver adaptor.
If it was not upgraded to composite lights, it would have the original type M-Series tail lights that do not offer much lens area.
Also 24-volt systems are a mystery to most civilians.
Why make a light plug adaptor if you have no plans to connect it to a military vehicle.
