I've owned a bunch of gas trucks in my life, and bought my first diesel, a 99 Dodge, 3 years ago. I won't buy another gasser.
I double tow with my 28' 5th wheel with the 18' jetboat on the back of it and still do about 14 mpg. Try that with a gas truck and see what your mileage does.
Besides, I love the smell of diesel in the morning...
