The GMC has a slightly nicer dash but I like the 4 headlights on the Chevy HD. It has a very chiseled look and the headlights are better. In terms of comfort the seats are the same shape. I have done 800 miles in one day on my HD.... and get 20mpg on the hwy.

I love my 2015 HD.

Nice truck Ben, CONGRATS

Speaking of paint chips, the Weathertech mudflaps are fantastic! I spent the weekend in New York and its all dirt roads where we have property. They work great! The low ground clearance of that stupid DEF tank is another issue though.

Its a shame to cover up that leather but there are some great seat covers out there these days.

x2, the weathertech flaps are awesome. So are their floormats.

However, I've had the flaps on mine since it was 2 days old, I can only imagine what the rockers would look like without them, considering how the paint on rest of the truck has held up.
