Hey guys, I just bought a used 2004 Dodge Ram 2500 and it came with a gooseneck ball hitch that I want to remove, but I can't figure out how to remove this particular kind. All the Youtube videos I've seen show don't have this kind of attachment, and I can't figure out how it works. I've attached some photos. There's a hole in the top of the hitch that's filled with grease. There's a lever on the side and a warning label that makes it sound like you're supposed to pull the lever to release the hitch, but I can't get it to move, even after spraying WD-40 around all the parts I could think of. The parts underneath the truck just don't look like anything I've seen before. Anyone know what the heck the brand is and/or how to remove the hitch without taking off the whole setup?
