Hank B replied to Hank B's topic in 6.6L Duramax Diesel & Allison Powertrain (L5P/MGM)Thanks Davester - this will be my first diesel. I understand they can take more power to start than a gas engine.
I’ve got a 2021 Silverado 3500 on order with the Duramax engine and it includes the dual battery and dual alternator option. I’m wondering what advantage this setup offers besides the obvious redundancy. Can one battery be isolated to support only specified circuit(s)? I’ll be towing a large 5th wheel RV and am wondering how to make best use of this setup. Thanks in advance for any information you can provide.
All - I have a 2021 Duramax on order; it will be my first diesel. I'm wondering if the fuel filler inlet on the truck will allow the larger diesel fuel filler hoses that are used in the fill lanes at truck stops for the big rigs? Any info is much appreciated!
