"side" ladder rack?

i did a search and up came tons of DIY stuff, but i still didn't see what i want.

looking for a ladder rack that mounts on one side of the bed, maybe using the existing rail system.

i don't want the permanent kind that screws to the body/frame, it's for occasional use only.

does somebody make this?

 

Whaddaya know, that’s the kind!

I wish there was a photo of a Toyota application, but that’s the closest I’ve seen.

I don’t want the full cage because it’s only for occasional use, and I don’t have the room to store a larger cage.
