The heavy gas trucks do get terrible mileage, but that's offset at least some by the cheaper oil changes and the fuel filters you have to do on diesels. And the 6.4 supposedly does a little better unloaded because it has cylinder deactivation. Still, you're definitely going to be paying a bit more for fuel.

2013 Silverado 2500HD 6.0 gas engine here. What's so terrible about 16-17 mpg highway and 10 mpg towing? It may not be ecoboost or diesel economy, but with today's gas prices, I can go a long way on $1,000.
I get that city with limited freeway and no highway driving. Highway I get 22 if I stick to 65-70. That's a material difference. But like I said, the towing range may be the bigger factor, especially if you put a transfer tank on the diesel.
