2024 Duramax Fuel Mileage 2024. Going next week to order my truck, and i'm seriously torn on which to get. Does anyone have any real world data on the 2024 6.6 gas v/s 6.6 diesel fuel economy.
Interior, comfort, and cargo pickup trucks have a wide spectrum of interior configurations and available. Current truck is a 2014 duramax with the 6 speed.
