2005 Ram daytona pickup real gas mileage ?

Lookin at a 2005 Ram Daytona edition truck , 4x4, regular cab, 5.7 Hemi,automatic, the website claims 11/13 mph! just wondering if this is real world or a government estimate? Anybody have one that can help me out! any way I can make it better? Found a really clean one ,but the mileage kinda scares me! Thanks!

I think that mileage is a bit optimistic. You should be prepared for closer to 10 and maybe 12 on the highway. They aren't exactly what you would call a mileage maker by any means. My 2003 Hemi regular cab short bed gets 12.5 if I'm lucky and it's a two wheeler. I will admit using the cruise I did get 14mpg on a long trip.
