I've driven nothing but diesels for 20 yrs.
BUT, the truth is anymore with the extra cost of diesel, plus def fluid they all take now it will be a minimum of about 150,000 miles before you ever break even on fuel savings.
Diesels are now 8k-10k higher than the same truck with a gas motor, all else being equal. Yeah they have great rebates on the diesels but you can get the same deals on gas 3/4-1 tons here.
I also don't trust these smogged down, EPA restricted diesels like I did the pre-2007 trucks.
Unless you tow constantly or plan on driving the truck 200k+ miles you'll likely never see an economic benefit anymore from a diesel.
