I have to say that most
I have to say that most people who own 1/2 ton trucks don't tow as much as they act like they do. Some people never even tow but if you don't drive 70 - 80 mph towing 10,000 lbs with a gas motor you can get reasonable mileage. I have a 13 F150 with the EcoBoost and I've gotten 11.2 mpg towing 10,500 at 60 mph. Yah it's a little slower but do you really NEED to get to your destination at warp speed? Not trying to argue that diesels aren't more efficient but if you don't tow that much it's going to take a long time to pay for the difference. For me I'll just drive a little slower and enjoy the drive and save on gas a little too
