I am looking to buy a chevy or gmc diesel, I have heard a bunch of stories about what motor is best. I am interested in milage only. I heard that the 07 has all the emisions controll and doesnt get as good mileage, but has almost double the horse power.
I am a weekend camper with an 8000lb trailer.
I am not pulling a backhoe or anything like that.
05, 06 or 07????
And why?
