Quite a few of your negatives for diesel no longer apply. Modern diesels are quiet, don’t smell at all, and have 14,000 or more mile oil change intervals. Also, you get almost 100% of the original extra cost back when you trade or sell.
So it's a personal deal, Here's what I found when I looked into it, and when I have driven post DEF diesels.
For me, for my buying, for what and how I use the truck, the drawbacks modern (post DEF) diesels have, is totally not worth it for me.
According to Ford the latest diesel 4x4 F350 when driven in dusty conditions has a 7500 mile oil and filter change interval with 13 quarts of oil. And now you also have a DEF refill. Which balances out the two quarts less oil it takes over the 7.3
Base line operating costs are going to be pretty close, though the modern diesel might take a slight edge due to the better MPG.
The modern diesels are still very dirty, even with DEF and other emission control devices. Tail pipe emissions are still very high. But because the trucks fall into a different emissions class it's hard to find data on them vs what you would find on a ULEV or PZEV sedan.
And they do stink, Diesel as a fuel stinks, and the trucks while running stink.
Granted no where near as bad as a stock well running 7.3, but they are still bad.
Resale value doesn't really apply to me since I keep my vehicles a very long time. which is why I didn't bring it up in my first post.
My Taco is an 2003 and I bought it new. I have two motorcycles that I've kept for 25 years and one that I've had for 40 years.
I expect to keep the taco until the plastic bits are breaking so frequantly that it no longer makes sense to keep it, same with the current F350.
But yup you are right you do retain a higher resale value, but no where near 100%, it's much closer to around 60% or less within the first 5 years or so but then those trucks all had about 100-150K miles on them.
At least that's been my experience with the shop trucks and vans I've been around.
Not all is bad. A modern stock, post-DEF diesel is much more quiet over the 7.3. it's a world of difference being in the cab, plus most of the new trucks come loaded with a lot more sound deadening techniques that just were not used back in the 7.3 days.
And they make a whole lot more power compared to the 7.3, and if you are willing to chip and delete them, it's really astonishing the power they make, but then they are very much back to being loud, and stinky and dirty and potential ticking time bombs when it comes to poorly built tunes.
I know there's a hardcore diesel cult, people love these things, and for good reason, if you really need one, they are the right truck to have, and if you really need to be convinced you need one, there are a lot of good reasons to use to convince yourself to own one.
But there are some serious downsides to the diesel power-plant, and it's only going to get harder as time goes on for diesel. I anticipate diesel tax and other fee increases, like we saw in CA this year when the taxes jumped $.22 a gallon. We are especially due for a federal tax increase and more states will jump on the increasing taxes and fees for diesel bandwagon.
