The new Sierra HD Duramax with the Allison 10 speed is sheer perfection sheathed in metal. Smooth, powerful, reliable, and beautiful. I love the simplicity of the infotainment, the Bose sounds great, and this truck gets looks. Resale value is insanely good as well.

Really enjoy my 2021 GMC 2500HD Denali. Great curb appeal, fantastic pulling power, very roomy, lots of utility in the cargo bed, helpful lighting everywhere, tons of improvements over my 2014.
