I am considering buying a 2500 Sprinter, extended with high top. I am a self employed home remodeler. I currently drive a 91 Chevy Grumman, P30 van. It only has 72,000 miles on it. It's running good now but the gas milage sucks. I'm getting between 8 to 9 miles per gallon. I've been working out of these types of vans for 15 yrs now and like the room and the ability to carry all my tools with me. It's rated a little over 1 ton. My brother-inlaw, who is also self employed, said I should look into a new vehicle for tax purposes. So, I guess what I want to know is, what kind of mileage should I expect from the diesel? Is it really worth all that money? I'll only be putting on about 10,000 miles a year. How reliable are they? I won't be towing anything. Thanks, Stush.
