Can we discuss pros & cons re gas or diesel? We're still looking at Bs. Some are gas, some diesel. We don't like the higher $/gal of diesel because it would offset any real savings from the higher mpg...
"The gasoline engine would not be penalized in the high altitudes because of the turbo chargers."
Maybe, it depends. The Chevrolet Express Van B has more horsepower at 10,000 feet than a Sprinter, but you can't use it indefinitely driving up a very long steep grade on the interstate (not a lot of them). You have to slow down while the Sprinter drives by because the cooling system won't keep up with the heat.
