Hello, I plan on towing a car 1,000mi (each way) with my 2020 GMC sierra 5.3, 10sp tranny. Car (Mini Cooper) + trailer weight = 5,000 lb, truck listed as 9,400 lb max. Manual said to let the truck idle before shutting off during long hauls, etc. was wondering if you folks have any other recommendations. My first truck and first time towing. All lifters replaced at 5,800mi (2 months ago), currently have 6,700 mi. Thanks

Posted this elsewhere on the site: How many engines are being affected by this, is it "not if be when" scenario? I was planning on towing my car (Tail of the Dragon) 1,000mi but don't feel confident with the truck. (2020 Sierra 1500 5.3 DFM, 10sp tranny, build date 9-20-2020 Roanoke IN). I don't want to be stuck that far away and have to pay U-Haul $1,200 to come pick up their trailer then drive the car home. FYI: Asked GM about the lifter issues and they kept saying "there's no recall on your truck".

My truck was built Sept 14, 2020 which appears to fall into the range.
