Went to a new Lesco location in my area for their open house. Brought my Isuzu so I could pick up some fertilzer, and the truck got some attention and I got to talking to one guy who also owns a Isuzu. He owns a late model Isuzu with a 14 foot box with a dovetail, and the 190 hp Diesel engine. He tells me it doesn't matter how he drives the truck, it gets 10 miles to the gallon like clockwork. Meanwhile.... my gasser has more power, better acceleration, less engine noise in the cab, cheaper to service, cheaper to buy parts for, cheaper to rebuild or replace, much easier to get serviced, costs thousands less to buy, and costs less for the fuel itself. And I am averaging around 9 mpg. A one MPG loss over the diesel, which I do not think is worth all the drawbacks of the diesel. For the average person, I do not see any reason so choose a diesel engine in a new Isuzu NPR. For used ones, I would be tempted to choose diesel over the old Chevy 350 Gas engine option they used for years, but not over the new 6.0 liter gasser they offer now. A week ago, a friend who is a dentist, and also a pilot felt something weird as he landed his airplane as a airport 30-40 miles away from his homebase airport. Turns out the landing gear attachment points inside the plane had cracked and the gear was ready to break at any momment. So we pulled the wings off it, and then put the wings in a U haul truck and rolled the plane itself onto my Isuzu, and we transported it to his house on Lake Norman for repairs. I had a 160 thousand dollar airplane on my truck and didn't bring my camera!!! Anyway, driving out to that airport empty, and then hauling the plane at 55 mph or less, and then driving home totaled over 140 miles and I averaged my milage after that trip and was close to 11 mpg.
