Diesel is often looked at as being smelly, noisy, and many think the only place for it is in a tractor. The truth to diesel vehicles is that they are tedious, clanking, smelly, although they are cheaper to run than gas.
However, there are some automobilists that still complain about the engine's weak power, specially when accelerating from a full stop. What you may not be careful of is the fact that a diesel motor engine can be tweaked to give more power without harming the fuel economy.
With trucks, diesel motor is normally the leader over petrol engines in terms of operation and miles per kilometer. The Indiana BMV (see: http://www.dmv.com/in/indiana) says that diesel trucks will get more kilometers than gas trucks, and the price for diesel engine is a bit cheaper than gas these days. And with gas prices on the rise, diesel motor will stay to command for a very long time to come.
