Vintage Ad: 1962 El Caminchero Travel Trailer – It Attaches to the Car’s Rear Wheels – Revolutionary!

Fellow CC’er Daniel Stern sent me this today, saying he was trying to post something to the Cohort for the first time. The only thing that caught his eye was the ’61-’62 Dodge Lancer towing this travel trailer. but that’s not what I noticed. What is going on here? Most highly unusual…well, it does say that it’s “revolutionary”.

I noticed right away how close up it is, riding right up on the Lancer’s butt. And I also noticed the twin castering wheels in the back. I thought it might be a two-wheeled version of the one-wheeled bumper-attached utility trailer. Then I looked again, and noticed the frame of the trailer, how it goes around the side of the Lancer and…attaches to its rear wheels! What the? I know that sounds nuts, but that’s what it appears to be doing. And that certainly would be a better place to put the weight than the bumper. Or would it? So much for reducing unsprung weight.

I Googled “El Caminchero” and found this other ad, which confirms it: “Within 2 minutes one can attach to rear wheels or remove”. Unbelievable. This is the first time I’ve ever heard about something like this. I can’t see it in detail, but presumably it has a freely-rotating hub in the attachment.

This is the only thing I can find on the web. Maybe someone can find the original patent.  In any case, this is truly mind expanding. I would never have imagined such a type of hitch existed.  One does wonder why it appears to not have caught on? Did it affect the car’s ride or handling? Some other issue? Hmm…

Update: here’s a more detailed picture that was left in the comments. And more pictures and the patent drawings are also now in the comments. Thanks!
