If you do not want a truck laden with emissions equipment, don't buy one. It's really that simple. No one 'needs' a new truck; not one single person on this planet is going to die or be severely injured in someway from not purchasing a new vehicle. This obsession that people have with buying a new 50k or 70k truck every few years is just as big of a problem, if not more so, than what comes out of the tailpipe.
Further, studies have shown that emissions from diesel passenger cars and trucks only contribute a small fraction of the actual contaminants, claimed to be polluting the atmosphere. Power generation is nearly a third (30%), manufacturing exceeds 20% and all transportation, including jets, trains, 18 wheelers, ships bringing millions of tons of crap from China everyday and even buses and taxis, make up about 25% of the total.
So instead of saddling a new $50k pickup truck with thousands of dollars of emissions equipment, requiring new hardware and a new chemical to be manufactured and added (DEF), thereby decreasing reliability, increasing maintenance costs and lowering the fuel economy of the vehicle, which simply results in more diesel being burned to go X number of miles or kilometers down the road, let's stop being consumers.
Think about how many factories have been built to build all of these new cars and trucks, and all of their associated parts. Think about how many semi-truck loads full of crap come to your local box/chain store every single second of the day. Think about how many ships come into ports from countries 10,000 miles away so we can have oranges in the middle of winter. Think about how many new Super-Walmart, Dollar General, Fred Meyer, TESCOS, Bunnings, Home Depot, Target and Lowes stores have been built in the last few decades.
I am not a greenie or an environmental whacko, but I do have a degree of common sense and can think logically. Filtering what comes out of the tail pipe of a Dodge diesel truck, is NOT the solution. Severely reducing consumption, development, exploding populations, home and commercial building, burning bunker oil/coal, and freeways choked with traffic for many hours each day, is.
People are the problem and as long as we continue to build houses, consumable crap and new cars at the rate of many millions of units per year, we are polluting the planet faster than it can repair itself. Buying a 15 year old used car that gets 30 MPG is infinitely "greener" than buying a new car with the latest emissions equipment screwed onto it, that gets 10 - 15 MPG, I assure you. Every single part on that new car or truck had to be manufactured; all of the glass, plastic, wiring, sheet metal, rubber, copper, aluminum, polyester, foam, vinyl, and so on. Where does all of that come from? Factories around the world churning out pollution then burning fuel to get those parts to the factories making cars, who then put them on a transport truck, which is hardly fuel efficient, to take them to a car dealer, so they can be consumed by you.
We can't keep doing the same things over and over again and expecting a different result. The Western 'consumerist/consumptionist' mentality has to change. That is the solution, not diesel particulate filters and Ad Blue.
If you insist on purchasing a new or nearly new vehicle, buy it in the name of a trust, LLC or 501(c)3. The driver's name is not revealed, as he/she is simply an end user, borrowing the truck if you will. Therefore any issues with the tuner releasing a customer list, which is about as 1984 as you can get, simply vanish. If you don't have the funds to pay a lawyer to do this or the private trust cannot pay cash for that 2020 F-350 you want so badly, maybe you don't need it after all.
