I was about to give up when I visited a nearby farm implement shop -- they had a welder with years of hitch building experience and he built a custom receiver hitch from Reese parts that looks factory while being less obvious than the typical bolt-on hitches. The photo below shows the hitch set-up and ready for its first 2,000 mile tour:
Had I not been able to find the farm implement shop that was willing to do the work, friends in the Kansas oil fields suggested that an oil field service company may also have a welder experienced in hitch building.
Good luck with your search for a proper hitch!
Thanks so much for your help. Since you have had experience using your Cadillac to tow, I have a few questions for you. I assume your Eldorado had the Cadillac 500 engine, so it had little problems moving itself and the trailer down the road. Did you complete any rear suspension modifications to accommodate the hitch weight, or did you leave the rear air suspension/coil springs as it came from the manufacturer? If you did leave the suspension as is, did you experience any issues with the air level system overworking or malfunctioning due to the increased tongue weight? With your trailer attached and your equalizer properly set up, did the car ride level or did it have a tendency for the rear of the car to squat? Also, did you make changes to the type rear tires (as in higher capacity load) you used, once you set up the car to tow?
Regarding the actual frabrication of the hitch, I am afraid you may be correct...most likely I will need to find a welder with hitch experience. You mention that your guy used Reese parts. Did you actually purchase a type III Reese hitch and then have him modify it? It sounds from your description that he didn't simply bolt it on, but possibly welded the hitch to the frame. Is this accurate? I can see where this would add addition strength to the hitch if done properly.
Thanks again for your thoughtful help. In the end, did your car perform as expected and to your satisfaction? In essence, the drivetrain you used could easily stack up against a 1/2 ton pickup of the day. Actually, it probably exceeded it, since that 500 engine developed so much low end torque. :-)
