Decisions....Gas or Diesel

I disagree. Gas is the way to go with that light of a trailer, you will be wasting money with a diesel. Will you use the truck when you are not towing? I ran diesels for years, and there was a definite advantage a decade ago, that is now not the case. The expense of maintaining the diesel, the huge difference in fuel prices, plus the advantage of fuel mileage for the diesel has grown smaller and smaller over the years with the EPA basically strangulating the advantage. A couple of years ago the 6.4 was premium fuel only, now with a light load like you will be pulling you can run regular fuel. I have towed with diesel and gas trucks for the last 30 years, and have a 5.7 Hemi Ram now I can still tow 11K lbs with no issues. They don't put the 5.7 in 2500's anymore if you buy new so the 6.4 is all you can get. That is my 2 cents, I am sure I will get lambasted for it, but there is no reason to run a diesel with that light of towing...
