2007 GMC Sierra 1500HD Classic SLE2 4dr Crew Cab SB (6.0L 8cyl 4A)


My 1500 HD is a beast on fuel. No matter what I do I can not get over 13.5 MPG. While I appreciate it's [power and towing abilities i did not expect to take such a hit on fuel economy. I traded a 1500 with the 5.3 which was getting 22.7 at highway speeds. Next time I will buy a Tundra which can tow just as much and when not towing get 18-20 mpg.

Best Features

Viability, Auto 4WD

Worst Features

Side window defroster are in adequate and side window tend to fog more often then not on the inside. ABS system is not as smooth as had imagined and am currently having issues with warning light coming on but only at highway speeds. This does not seem to be affecting braking
