When I am pretty sure gas engine will perform like other members experienced, I become diesel addict 30 years ago and will not buy gasoline vehicle period.
For me it is mostly economy, as 20 years ago diesel were under-powered and lousy performers.
That changed drastically with last 440 HP beast from Ford, who I used to move from San Francisco Area to Las Vegas.
Several grades in range of 7 to 15 miles, triple digits temperatures, yet the beast would pull 7000 lb trailer + bed load without dropping from overdrive.
Still delivering +- 10 mpg on such combo, while 12 mpg + with 6000 lb camper. All of that with only slight tire noise entering the cabin, so you can enjoy Opera music.
Diesel is the cheapest fuel at places where I fill up and for mountain driving you have new turbos closing the flaps to act as engine brake.
Not extremely efficient, but help a lot.
Than my diesel sedan, with 2 tons weight for safety will make 60 mpg at 60 mph.
Than check the resale value.
