Visiting Mexico with a truck and camper late 2018

This seems to be a pretty good source of info on Diesel fuel quality in Mexico:

Just an FYI, so I'm following too, there was a problem with certain makes/size of trucks and they weren't allowing them in, something about commercial size/weight etc, but apparently only at one or two AZ crossings. It was resolved last I heard.

Diesel fuel, have a few friends that go down there and diesel is easy to find, most trucks are Diesel. Quality, I'm assuming it's fine or fuel up at the border..

Here's a link to website, RVillage that has several posts/threads on it to that might help...

Hope that helps. You didn't say where or how far down to Mexico. Baja or the mainland..

Is it truck MY of 2018, the camper of 2018 or you plan the trip in 2018?
In the past diesel fuel in Mexico was the biggest concern with modern diesel engines. I am interested if that is still the issue?
I plan to visit Baja and wonder who has 1st hand experience with their late fuels?
I think your SRW is good for Mexico.
I've been there few years ago with a bus and on Baja roads I had about 6" tolerance between leaving my side mirror on opposite vehicle, or rolling down the end of pavement.
From the guy who could easy drive 6-700 miles on US freeways, I become exhausted after 250 miles day trip.
