New type of hitch made in USA

I had (new) a 1985 Chevy S-10 with a bumper like that. I put a ball on it and it towed about 3000 pounds with no problem at all. The truck was a manual transmission, no air conditioning, an AM radio only, and no carpeting. I had a shell on it and we used for a LOT of tent camping (except we slept in the truck bed with the shell over us). It was a great truck. I drove it more than 12 years and it died at a grocery store parking lot intersection. Engine literally blew up. It had so much rust on the doors and body, there was nothing left to salvage. I got $100 for it from a junk yard and they towed it away. I signed the title over right in the parking lot. But that bumper towed all kinds of small trailers!
