2007, 3500 van with 6.0L engine. This van is used as a electrical service van so the mileage age is atrocious, its loaded with thousands of pounds of tools and materials. I also keep a 4, two 6's, an 8, a 10 a 12 and a 28' extension ladder on it so you can imagine how aerodynamic it is. So I get 10.5 pretty much all the time. I love this engine its seems to have an endless amount of power. I regularly pull a tilt trailer with a scissor lift(about 9000lbs) on it and handles it no problem. We also have Fords and I think they are junk, I'm not a Chevy guy or anything, I tend to prefer Japanese vehicles but when it come to full size vans I love my express. My company tried 5 or 6 Sprinters and they gave up on them. They refuse to buy them anymore because they are money pits. I never had one myself. I'm very interested in how the new full size Transit will compare.
