2011 Sierra Hd Towing Mileage

[Bear68]

Since I took delivery on my 2011 Sierra HD gas'r I haven't had a chance to pull our camper. Anyone been pulling anything with a 2011 GMC and what kind of gas mileage are you getting? With the added weight due to the frame and suspension improvements, I am really interested in what mileage will be.

When I tow with my 09 I'm pretty sure I can actually see the needle moving towards E. Is that bad?? .....

My previous truck (tundra) got 7 mpg pulling our old camper so I know we will get less with the Sierra and a heavier camper. I am figuring 5-6 mpg. I guess we'll find out this spring. With the additional 700 lbs of added weight GM made with the frame improvements etc. didn't know if anyone had a pre-2011 model and now has a 2011 model for comparison. with these gas prices, going to have to work some OT before our summer vacation!!

My previous truck was an 07 Vmax with 4.10 gears and towing my travel trailer, I saw between 9-13mpg. Not quite the same truck, but you'll be in that same window.
