Item: Bumber pull hitch - 50's style.
Daughter #1 was on a photo-ramble and found and old filling station and some old cars and got some pix and and photo compositions.
Here was what caught ol' Red Rovers eye.


Here is a monster system and good luck in replacing this system. This Mor-Ryde is an O.E. installation that is directly welded to the chassis and the springs attach directly to shackles clad in a compounded rubber block. Upgrades look to be difficult and replacements are actually a conversion.

Fenders were also cheap plastic and no paint necessary on these and some other components. When you think about it there is no paint put on any of these and that step in production is eliminated entirely.
After a while the sea salt environment along the coast wreaks havoc and what comes in for repair is virtually not worth the cost of a new replacement trailer. They don't last long. 

O.K. you are thinking, why not use a harder wheel. Nope, same result. This is a bolt through jack and the way the jack is mounted and how it works will separate the two mating plates apart where the thing is u-bolted to the tongue.
I think we have something that will work and on location says they will try it and I will update this post when it actually solves the problem.
