I'd be pretty upset with a dealer that didn't install them for me or didn't inform me that I should install them if I plan to tow a trailer.
When I bought my truck it came with an HD towing platform with a 2 1/2 inch receiver. The TT's safety chains wouldn't fasten to the platform because the heavy duty metal and holes were too thick and too spread out. I went back to the dealership and they claimed they had never had a customer with that problem before (which I found hard to believe). After weeks of thinking & searching, I found over-sized 5/8 inch Quick Links. When I went back and shared that information with the service manager, he acted like he couldn't care less. In one ear and out the other.
