I expect (and hope) a diesel could make it 400K and gas might make it that far. I think the bigger hurdle is the 20 year mark. My "new" truck is from 2002 so maybe the guys with new trucks can comment. As you look under the hood at the Ford gadgetry on a 2017 truck, I wonder if some of those highly sophisticated electronic components will be supported by Ford or anyone 20 years from now. Should the OP be setting a shorter time goal? Maybe 15 years? Remember to be legal you have to meet emissions standards of the time a truck was built so you can't legally hillbilly rig a truck to make it run. In other words, all of those fancy parts will be needed.

 

I recently came out of a half ton Toyota Tundra to a an F250 Super Duty with the 6.2 gas engine. I won't even attempt to debate the need between a diesel and gas as that horse has been beat many times.
I will say that for me, I wanted to ability to have a larger trailer/5th wheel/truck camper in the future should I want it. I did not want to be limited to what trailer I purchased by the truck I owned. That being said, I know I did limit myself due to the fact that I went with the 6.2 gas and not the 6.7 diesel, however, I will never need a trailer that big that I would have to have a diesel to pull it.
As a daily driver, it has as tight a turning radius as my Tundra had and you just have to get used to driving a larger truck which to me is not a big deal since I don't live in a big city and have to navigate the big city traffic.
I also like the feel of driving a heavy duty truck versus my half ton.
That's about it for the decision making process I used when making the decision to go with a Super Duty.

 

Like me! I use a little half ton all day every day

 

You were the example I was thinking of. I think you're the second fleet owner of that thing, right?

 

Yup. It has been a wonderful truck.

 

Everybody needs at least one hd truck in their lifetime.... If you like it then get one but I'll say this if you don't need the diesel motor then stick with the 6.2 it's a great platform.

 

Get the best of the 1/2 and 3/4 ton worlds...... a Nissan Titan with the Cummins

Notice I didn't say the Ram EcoDribble Patiently waiting for Ford to play in this particular sand box....

 

I do way less work with my truck and tow very seldom. I came from a 5.4 F150 to a gasser Superduty and regret it a year in. I want to trade but resale sucks so I'm gonna wait about another year and get a 17' with the new Ecoboost.

Mileage is terrible, ride is rough and cab is smaller; not as much room n the rear to put stuff when seats folded up. It looks great of course and I thought this would make me over look the downsides of upgrading.

My 6.2 works hard to do things my 5.4 did with ease. Climbing hills at 70-75, hauling trailers,towing my side by side. It's a strong engine but makes it's torque real high in the powerband. It downshifts more and the solid front axle is not as comfortable to drive.

I knew most of this going in but bought it anyway. It's a nice truck and I am picky but should of stayed with a 1/2 ton. It's my fault, not the truck. If I do a 3/4 again it will be a diesel.

 

Yuk. That TitanXD is hideous. Not only that but many people that have driven them report that the diesel in it is a bit of a dog. The consensus often seems to be that the TitanXD has the weaknesses of both a 1/2 ton and 3/4 ton and none of the strengths offered by either.

Side comment on the Ram EcoDiesel, I think its awful to drive. I looked at one for the fuel economy when I bought my 2015 F-150. After driving it I knew I'd never be able to stand it. The thing is just horrible to drive.

I'm not a big fan of the 6.2L engine. I generally think I'm the only one who isn't. In an F-150, I'm all over it. In a crew cab or crew cab long bed SD, not so much. It does get the job done but as you noted you have to rev the **** out of it to access its potential. The 6.7L diesel's low end grunt and flat torque curve make it a lot nicer to drive. As for the cab of the F-250, it's actually got more room than the previous F-150's did. Compared to the current F-150, I feel its roomier up front, head room not withstanding. The center console is thinner as are the door panels. I've got more leg room as a result. In the back seat, you lack about 4" of room but I feel the storage amenities make up for it.

As for the mileage, I knew it wouldn't be good. That said, I'm not doing too much worse than I did in my half ton and in some cases I'm getting better mileage out of my diesel. I'll agree on the ride quality. That said, the 2011+ Super Duties ride really well for 3/4 and 1 ton trucks. The steering is a bit heavy when you are used to half tons, but otherwise the driving experience is excellent.

 

"It does get the job done but as you noted you have to rev the **** out of it to access its potential. The 6.7L diesel's low end grunt and flat torque curve make it a lot nicer to drive."

And that right there Spamfritter is the big difference between gas and diesel engines. Some like it and some don't. I would be willing to bet you like that higher rev in your mustang though, correct? I had a 7.3 back in 2000 and did like the low end torque at lower rpm's. With my new 6.2 it is a completely different truck and driving experience but I really like it. I love those diesels, just can't justify one for my needs.

 

If you're not going to go heaver in towing or hauling than you already do then the F150 eco boost is good enough.
If you have plans on going a little heavier than current, go SD. Gas and Diesel haul about the same
- but just consider -
Gasser has to work harder and less mpg empty or loaded
Diesel doesn't have to run as hard to do both, better MPG on both, but more $.
Got my f250 before my previous TT and now I have the 5er below. Didn't have any plans initially for either but when we decided to take the leap having the tow vehicle wasn't an issue. Better to have it and not need it than need it and not have it.
Also, in Ohio, on the hills, in the snow, hauling firewood and coal, 4WD for sure.

 

That may be a great drivetrain, but the problem is, you would have to look at the thing everyday. Nissan ruined a decent looking truck with the design change.

I love my 6.2 gasser. I have no real need for a SD, but was glad I had it when pulling my travel trailer 1600 miles on vacation across the mountain. It handled 8500 lbs no problem, got 9.5 mpg doing it, and the truck drove great through the curves and at highway speeds. But my daily trip is just under 20 miles round trip. If I had a 66 mile daily trip, I would have bought the f150 I was originally looking at. I would even be looking at the 2.7 ecoboost with a heavy payload package real hard if I was you. Those are outstanding little motors, and punch way above there weight class. More power and torque than your current 5.4, with an updated chassis, getting a lot more mpg's. If the extra money on gas is not a big deal to you, then SD it is, but if I had to drive the distance you say, it would be the 150.

 

Actually, for basic daily driving you don't have to rev the Mustang's engine very high to get the thing moving pretty good. My Civic Si on the other hand was similar to the 6.2 in that you had to really get the revs up to make the car feel powerful.

 

Just as an anecdote, I was in Honolulu this past week. 87 Octane was $2.65 a gallon, diesel was $4.29! I did see quite a few fleet SD's but the were all gas, I think the only diesels on the island are busses and service vehicles. I just took this thread even further off course, my bad...
