[70rs]

For what it's worth when I sold at a local Chevy dealer that particular store sold diesels 5 to 1 over gas.
Now up here we have real live mountains. And in this county A LOT of livestock moving (heavy towing often).
That being said, those new diesel sales were usually to the people towing several times per month. That alone tells me the towing issue is in favor of diesels hands down. No brainer there.

But for the average guy who commutes, hunts, camps, tows once in awhile or just likes driving a truck the gas motors are fine.
High mile diesels take a bit more maintenance and that does cost more on average than the gas trucks. Even the oil changes and air & fuel filters can be double or more than a gas motor.
I have owned both a 2500 6.0 gas and a 5.3 1500 (current)
And both were VERY cheap to maintain.
The few times I wished for more power with either really didn't justify me buying a diesel.
The boat I towed with the 6.0 (with close to 200k) was about 7000 pounds fully loaded including trailer.
Only on the steep and long grades did I want more grunt. But that was so I could cruise at 75 instead of 55/60.

Sorry if my rambling doesn't help. But I just didn't NEED diesel. But I sure do WANT one.
