I too have the Beat LT TCDi in Sand drift Grey. I too am 6' tall and I agree with your points. Your FE is excellent. I haven't checked my FE yet. I've covered 800 kms in the car. I'll start checking it after I finish 1K. What tire pressure do you keep?. 32 psi is what is recommended, however, what I found was that the car was delivered to me with more than 40 psi in the tires (perhaps to boost FE, not sure). Did you get the above FE with 32-psi or with something higher? Also, since you've been on stock tires and the stock steel rim, can you let us know if you faced any sort of issues with these? I too am planning to stick to stock for the first few years. Also, what % of your driving is with A/C on? At what RPM do you generally shift? My gear shifts are between 2.5k and 3k when I'm really throttle happy, I shift mostly at 3k. How has your experience been on hills and hairpins? I find the A-pillar side visibility pretty annoying.

For being so big, the truck gets decent fuel mileage. It has a 6.5L Duramax diesel and gets around 20 mpg. It hasn't met a load it couldn't haul or pull, but is also great as a daily driver. You can see everything from the drivers seat, even though it is so big, since you sit up so high. It looks awesome, intimidating and tough. The 8 foot box is big enough to fit a few dirt bikes in it, even with a topper on!

The positives of the Chevrolet truck are many and include leather seats, decent gas mileage on the highway, OnStar, and a wonderful stereo with the ability to play songs from my iPhone. Another positive is the amount of room in the cab is generous, considering I purchased the double cab. The upgrades on the truck were worth the extra money.
