I hate getting such terrible gas mileage too but when the price of Hybrid technology goes down and it becomes more mainstream/more affordable, i'll probably upgrade to one. I get 10.5mpg in my Esky and 14.9 in the Avalanche so I personally think 15.3 is good considering it's a 6+ ton vehicle. The TBSS is sick so if you don't mind losing the interior space and want to save some cash, i'd say the logical choice is to sell it and buy the TBSS : / but the interior in these GMT900 vehicles are sick!
Not 6 tons
Almost 6k lbs....3 tons. A Tahoe is about 5,800lbs. That would be a BIIIIG GMT900! haha
Yeah the Esky has the 6.2L (right?) and full-time AWD. One reason I don't understand this full-time AWD thing in an era where they are trying to get every last MPG. It is good for its size, for sure. I just thought it would be in the 16s. Revised EPA estimates are 14 city, 19 highway, and 16 combined. Trying my best to stay in 4 cyl mode as much as possible 15.3 is my average from March until August. That isn't why I'm thinking about selling though, like I said the smaller Grand Cherokee gets similar mileage because it is AWD. I was refering to the fact that the much more fun to drive TBSS gets about the same and it has AWD and a yummy LS2. I wish the TBSS has selectable 4wd and 4 cyl mode!
Oh important to mention the TBSS wants 93 octane and the Tahoe is happy on 87.
Chances are I will keep her, they are great trucks, but just talking it out.
