By Sailer on
Vehicle2008 GMC Sierra 2500HD SLT 4dr Extended Cab 4WD SB (6.0L 8cyl 6A)
Review9.5 mpg city 10.7 highway. Door handle under armrest is a pain to get to. 5.3 engine would give enough power as I run empty 95% of time Needed 2500 to plow snow. Needs cup holders in dash.
Best FeaturesHandles V Plow with ease. Large windows gives excellent view all around
Worst FeaturesFor better fuel economy. Drop out 2-4 cyl for highway driving like smaller eng. Large mirrors on all trailer tow packages. Flex Fuel
