I was rear ended last year about this time and I made her insurance company replace the hitch receiver on my truck to prevent any risk of failure. I started pulling a relatively heavy camper after that and I noticed that the receiver cracked. The original one never failed and I towed the Camaro many times for 5+ hours at a time. I'm guessing I just got a bad one and it was a freak thing. I replaced it with a heavier rated receiver (1600 lbs tongue weight/16000 lbs trailer weight) and had GM warranty the one that was installed last year (it had a 2 year warranty). This is rated at 1200 lbs tongue weight (with a weight distributing hitch) and 12000 lbs trailer weight. The hardware is still in the bags and it is looking for a new home. I believe GM said it fits trucks from like 2005 and up. GM part number - 84152031. They run $295 (discounted retail) from my local dealer.
I had to send the old one back in the new box to the dealer, so I'd like to stay with local pickup (or meeting me somewhere, I'm doing some traveling to Wisconsin and Virginia this year (through all the places in between). Located in Columbus, OH.
It's this one:
