❓ FAQs (Frequently Asked Questions)
Which engine should I choose — gas or diesel?
Go with the gas 6.6 L V8 if your towing needs are moderate and you want lower complexity. Choose the Duramax diesel if you plan to tow heavy loads regularly — its torque and efficiency under load are superior.
Does diesel reduce payload significantly?
It can lower payload modestly depending on configuration, but the tradeoff is much greater towing capability.
What’s the difference between conventional and fifth-wheel towing here?
Conventional uses a rear hitch; fifth-wheel / gooseneck places the trailer load over the bed, allowing higher tow ratings (e.g. ~22,070 lb in crew cab diesel).
Do all trims get full tech and safety features?
No — lower trims get the basics; higher trims unlock the full suite of cameras, Google UI, trailer views, and advanced driver aids.
Where can I see official trim and spec breakdowns?
