So I'm looking at the the 2019 towing capacity, and for a Chevy Silverado 2500 Crew Cab 4x4 with a standard bed and the 6.6l Duramax engine it's rated at 13,500 lb's. But the new 2020 Chevy Silverado 2500 with the same configuration is rated at 18,500 lb's.
What changed? Frame improvement? Bigger drive train?
