Thanks for posting and I'm not surprised.
Interesting story. We used to tow with a '76 Impala (stock 350 V8) and our last long trip with it, was in the mid-90's. We towed across 3 prairie provinces and the Rockies (BC) to Vancouver Island. We then drove it back, towing our trailer across Washington, Idaho, Montana and North Dakota, then up to Canada.
Not one issue....a heat wave where temps hit 109 F (Montana)...well one issue. The cheap dept. store tires we had, needed to be replaced due to their inability to handle the heat.
I think people who dismiss big Chevy rear wheel drive sedans...have never towed with them.
