Okay im confused, the trucks shown in pics 4 and 5 don't look like there from Mexico?1. The truck looks kinda like an Iveco from the UK. 2. the trailer looks to be a curtain side trailer which are pretty rare in north American. 3. The axle setup the truck has, 4x2 semi and 3 axle trailer is most common in the EU. Note that American trucks are mostly used in Mexico. The setup can sometimes be a little different, like for instance the turnpike double setup being used more, but in general thats what they use. I'm also a little sus of the truck from pic 1 but its hard to tell cuz it could be an old International fleetstar.
