2004 Chevrolet Silverado 2500HD 4dr Crew Cab LS 4WD SB (6.0L 8cyl 5M)
Performance, outstanding. Acceleration with a full load or with a heavy trailer is all I could want. Comfort. This is a 3/4 ton truck, so with that understood it is very comfortable. We have driven 24 hours straight more than once with no complaints. Fuel economy. Duramax/Allison gives me 17.5 mpg since new with 50/50 mix of hwy/city mi. 19.9 mpg with light load at 65 mph. Amazing for 3/4 ton 4X4. Fun to drive. Well, OK I guess, for a truck. Build quality, reliability. I have had no failures of any kind in 55k. Exterior design. Who thought up the stupid slant-eyed headlights? Ugly, ugly. There is little to find fault with, and much to like.
Power, torque, comfortable interior. I got the base fabric interior with the split bench seat; great arrangement. The power extending mirrors are great if towing a trailer.
Except for the stupid headlight design, nothing comes to mind.
