Every system in a diesel truck is in a gas truck. With the exception of the DEF (diesel exhaust fluid) system and DPF (diesel particulate filter) and on a gas truck the spark plugs and all related ignition system. Modern gas engine run direct fuel injection, high pressure fuel pumps, fuel rails ect.
The trucks components are the same? Transmission, differentials, transfer cases, fuel filters, cooling system, electrical. Capacities may be more on the diesel, but really paying 75-100 for an oil change compared to 30-40 is "HIGH COST". Your buying a 50k-60k truck and complaining about paying for maintenance while towing your 70k trailer???
Buy a diesel because you want one or don't, but asking people on the internet to tell you it's ok doesn't make sense.
When a modern vehicles brakes it's expensive gas or diesel. When a turbo fails in a diesel it expensive, when the turbo in a new Ford ecoboost dies it's expensive ,and it has 2 of them.
I hear you, but it is a bit more complicated than that.
I can buy 5W30 synthetic on sale all day long for less than I can buy a mineral 15W-40 diesel oil; no you can't run a diesel on gasoline oil. My 5.8L Isuzu takes 15.5 liters of that more expensive oil compared to 4.5- 5 liters for an equivalent gas engine.
The engine oil filter is also double, if not triple the cost of a gas filter. If you have a turbo, you probably have another set of inline oil filters before the turbo.
Then the fuel and water separator filters can be pricey and must be changed more frequently than a gas, as they do clog up.
Particulate filters on a modern diesel (not on gas motors) are very, very expensive. VW quoted my boss $4,500 for the filters on his Jetta TDI. Depending on the vehicle and how it's driven will determine how long an interval should they be changed.
Then you have DEF fluid and the modern day diesel emissions systems, like EGR valves. These systems have been in gas motors for decades, but only since 2007 have they been mandated for diesels. There have been growing pains with emission parts failing very early and often.
A fuel pump on a modern day gasoline vehicle you could buy for $100.00, while a electronic fuel pump for a modern day diesel could set you back $2,500- $5,000.
Also other components like transmissions and drivetrains are built differently for diesels and since the diesels are relatively scarce compared to gas models, these components are pricier due to their rarity.
