I am looking at a used truck to purchase.
Going to go with a 2005 and up Dodge 2500.
I am looking at going diesel, but I have a few questions.
I currently own a 98 ram 1500 with a 5.2L.
I literally only live 4 miles from work and in 2010 I only put 5600 miles on my truck.
Is it not good to have a diesel if I live this close to work?
Too short of a run time ?
My gas engine barely gets warm by time I get to work.
Will the short run time be bad for a diesel.
I was only looking to go diesel for better mileage.
Should I look at a gas instead ?

 

If you're looking for fuel economy only, I'd pass on getting a newer diesel. You'll have DPF issues in no time due to never doing a complete regen cycle and in 4 miles you're not going to get up to operating temp unless you let it sit and warm up before leaving, effectively killing any fuel economy gains.

A 4x4 2500 diesel weighs about 7000 pounds empty (4-door). 1500 series gas trucks are a couple thousand pounds lighter, have lighter rotating masses (wheels/tires/axles/driveshafts/tranny/etc) and with MDS they could potentially get similar fuel economy, depending on your driving habits.
