Yes for sure many of the class 8 trucks are ASSEMBLED in Mexico of parts made in several countries including the Usa. Your Ford, Chevy and Dodge pickups are also assembled in border towns in Mexico. This does not qualify them as being "Made" in Mexico. They are still American Made Trucks.
I do not mean to nitpick or argue. The areas where US branded vehicles are built in Mexico are not "border towns" other than maybe Mexicali where Kenworths have been built for a very long time for the Mexican market. 23,000 trucks per year from the KenMex Mexicali plant built for and sold in Mexico. Most of the other plants are much further down in Mexico.
Can Moisheh or Briansue claim that level of experience?
I owned my own truck and drove both local and 48 states for almost 10 years back in the late 70s through most of the 80s. Different times. But I still like trucks and pay some attention to what is going on. We have been on the road in our motorhome for 11 years now with almost every winter in Mexico so we pay some attention there too.
The vast majority of the Class 8 trucks being manufactured for the NORTH AMERICAN MARKET are ULSD trucks. Whether they go to Mexico or not.
You may be correct but I tend to doubt it since it probably is not a good idea to run a vehicle equipped for ULSD on LSD fuel for very long. Many trucks run upwards of 150,000 miles per year and burning the fuel found in most of Mexico could cause some problems. The basic engines are the same but the equipment used by the ULSD trucks can be quite different than the LSD trucks. Even the cars built for the Mexican market can be different and some do not meet US standards so do not cross the border. Freightliner and International both build for the US and the Mexican market - but what they built do have some subtle but serious differences.
There have been a great many discussions here by people who know a lot more than I about what happens when you put LSD fuel in a ULSD vehicle over and extended period of time for extended miles. I seriously doubt Mexican trucking companies are buying ULSD trucks to operate on mostly LSD fuel.
Vehicles are built all over the world for different markets all over the world. In many cases they do not build the same vehicle for one country that they do for another country. Back some years ago I had a friend who would go to Germany to buy German made cars for the German market. He bought them to bring back to the US to sell to the US market. In order to sell them he had to do a number of modifications to make them legal in the US. Among the things I recall were side marker lights and something inside the doors to strengthen the door in the event of a crash. He had to do a number of other things I do not recall.
Vehicles built in Mexico go to different markets all over the world and they build them to meet that countries requirements. As far as fuel goes - at the point the US and Mexico do not have the same fuel requirements so they build differences into the units depending on where they are going. Much of the vehicle is the same but some things are different. You have to look very closely to see some of the differences.
As for the corruption issue: Mexico is like Switzerland compared to Cambodia and Nigeria and Egypt 3 places I have lived and worked, so I know corruption and I know it is all too easy to paint any situation with too broad a brush. Not every situation or official in Mexico is corrupt and to claim so is just the worst kind of nationalistic xenophobia.
It would be a great benefit to stop viewing our neighbor to the south through such a small lens. Mexico is a big diverse country and deserves more respect than it gets from some here.
I am sure that quote did not pertain to me as I don't think I ever get into the corruption issues in Mexico because I know next to nothing about it and have personally never had any problem or encounter with any corrupt official while in Mexico.
We love Mexico and I think are pretty much on record on this forum as we speak out about how much we love Mexico very often on this forum. We love the Mexican people and lots of things about Mexico and wish we could spend more time there and that we could find a way to better learn the Spanish language.
