I purchased a brand new Trailboss with the 5.3 V8 in June of 2019. In August of 2019, while hauling my 3000# pound boat on Interstate 65, the crankshaft in the engine broke. It had 5000 miles on it and I was well within towing/hauling limits. Has anyone else experienced this with their Trailboss or can I chalk it up to a bad part? I argued with Chevy and told them I wanted a new crate motor. They wouldn't do it and only agreed to repair the truck. They did increase the warranty to 100k miles on the powertrain. Has anyone else experienced this?
