Frequently Asked Questions:
How does the SLT make towing easier for a first-time heavy-duty owner?
The SLT’s ProGrade Trailering System centralizes guidance and monitoring, while available camera views such as Transparent Trailer View and HD Surround Vision help you line up the hitch, check connections, and keep eyes on blind spots with a trailer attached.
Is the Duramax 6.6L Turbo-Diesel V8 worth it if I tow occasionally?
If you frequently navigate steep grades, high temperatures, or long distances with a trailer, the Duramax’s torque and Allison 10-speed pairing provide extra confidence and smoother control. For lighter or infrequent towing, the standard 6.6L gas V8 is a great all-around performer.
