2024 Gmc Denali 2024 Duramax Dually. I bought it just because over the 2500hd but pretty much guaranteed i'd never fully max the load. The denali trim moves to second place in the sierra hd’s hierarchy for the 2024 model year with the introduction of the new denali ultimate trim, available for both the 2500.
This particular truck is a 2024 gmc sierra hd in the crew cab, long bed configuration. Available maximum fifth wheel/gooseneck rating of up to 9584 kg (21,130 lb.)†.
