My new ride is a 2015 Chevy Silverado 2500 HD Duramax diesel with Allison transmission. This thing is a BEAST!! No horse trailer yet (that's probably coming next year), but it will haul like a champ. I am so glad I went for the 2500. It won't even know that a 2-horse trailer is back there.
I LOVE DRIVING THIS I DON'T WANT TO DRIVE ANYTHING ELSE EVER.
I mean, listen to The Big Dog growl:
