True, that's why trucks are different, but privately owned trucks used as tow vehicles represent a tiny portion of world wide diesel sales.

Recently there have been several introductions of smaller effecient diesels in 1/2 ton and smaller US trucks. It is likely this trend will continue.
Diesels are born to work. They are scaled down industrial engines with longevity, effeciency and dependability. The more you drive and heavier you go the more you need a diesel.
Diesels will be around long after most gas engines have been retired, because they can run on less refined fuels including biodeisel which we can grow in an agricultural field or a pond. When hydrocarbons become more expensive, then we will be in the Age of Diesels for real.
The US has flirted with $4 plus per gallon gasoline before. Biodiesel is very competitive at those prices. It is a question of time before we get there again. The use of biodiesel made from algae is an ace in the hole. Then we will have an endless sustainable supply of energy for transportation.
Modern pickup diesels are not scaled down industrial engines. They are purposely designed for the task and longevity the need to fit. Maybe the โtractor motorโ diesels of yesteryear could be described that way.
The issue with renewable carbon-based fuel is that carbon is out of style and considered pollution. Supply is only half of the concern.

That's cute. Plus it only comes in a half ton (even cuter).
Compare the EcoBoost emission equipment to your cummins under the hood (cute) and then compare the EcoBoost exhaust to your cummins exhaust (even cuter).

It will be interesting to see if the Electric Truck manufacturers like Tesla and Volvo will make a light duty variant. Eg, instead of a 500 mile version meant to tow 80,000 pounds maybe a 400 mile unit meant to tow a 30,000 pound load. 400 Kw battery, lower profile, chargeable at a supercharger with dual Superchargers. They would probably have buyers at 100 grand. Donโt know how much of a market there would be though.
Probably huge!
Think of all the box trucks you see on the road everyday.

I want to preface this by saying I have never owned a diesel. However, from the reading I have done, it seems to me that one of the major draws of a diesel over a gasser is the high torque at lower RPM's. My Ford 3.5l EcoBoost engine produces 375 hp at 5,000 RPM, but it has its maximum torque much lower. It produces 470 lb-ft of torque at 2250 to 3500 RPM. I can get the diesel-like low range torque without the front end expense of a diesel, the higher maintenance costs, the astronomical repair costs, and the higher fuel costs. Sure, it gets lower mpg, but that is a trade off I am willing to accept. On top of that, it has 2 turbochargers that reduce the power loss at altitude for those times I am in the Rocky Mountains.
The advantage of diesel for me is the steady torque curve. Even when I had a little naturally aspirated model with less than 60 hp, it was capable of towing my fiberglass travel trailer through the Sierra Nevada's. I compare gas to diesel like a 2-stroke to 4-stroke: the two stroke has a lot of potential at higher revolutions in a narrow band, while the four stroke has less peak and spreads power over wider band. The 4-stroke attributes seem to follow this comparison against a diesel. Once forced induction is introduced, smaller displacement is required to make the same power and power can be generated at lower revolutions - This doesn't matter what type of engine is being boosted.
