I'm looking to get a new(2011 or 2012) diesel truck and am stuck between a ford or chevy. What are some of your un biased opinions? Which one gets better gas mileage for mixed driving?
I drove both and liked both for different reasons. Personally, I think the GMC is the better looking truck on the outside (minus the DEF tank hanging below the passenger door), but the Ford's interior is much better. Both make great power. I personally think that Ford makes a better drivetrain. That can be argued to death, but only time will tell how well they hold up.
GM's products are proven, but not necessarily with the emissions components. When I was tooling around and weighing my options, a fair amount of people were complaining about poor mileage with the LML, more than people who owned a 6.7 Scorpion. One of the guys that worked at my local GMC dealership did mention that they had a few unhappy customers due to lower than expected fuel economy. This was one of the deciding factors for me. Slight edge to Ford in the fuel economy department.
That being said, mpg is directly proportional to your right foot, terrain, climate and type of driving. I live in a hilly area in Pa, often make short trips mixed with the occasional highway trip and I'll see roughly 17mpg. According to the truck itself, I have seen as high as 24mpg during a 100 mile highway trip, but that's mostly because I was REALLY trying to get the best possible number. The people around me on the highway weren't all that pleased, but who cares. Around town numbers will be 13-15, just the nature of this beast. They are incredibly efficient at speed on the highway, but it takes a lot to get them moving during stop and go situations.
To be honest, you really can't go wrong either way. Both companies make a solid truck. When you drive each of them, you'll figure out what you like and don't like. I sat on it for a week or so, went back and test drove them again to confirm my likes and dislikes. I would be happy to have either. It's the payment that made me like the Ford a whole lot better than the GMC
Good luck picking one out! Let us know what you decided on either way.
