I have yet to hear of any RVers to break down in Mexico because of their particulate filter being clogged.
I am not sure that immediate breakdowns are the issue. It is my understanding that semi tractors that put on hundreds of thousands of miles per year in the US do have to replace these filters after awhile while burning 15ppm. I think the concern might be that 500ppm or whatever could significantly shorten the life of one of these filters - which I have heard are not cheap to replace. So to me the concern would be how the increase in sulfur by as much as 20 to 30 times the amount they are designed for might contribute to the eventual demise of the device.
I have heard they had the technology for emission control prior to the availability of 15ppm but that the technology would not/could not/will not work with higher ppm fuel. I have said for years that if you are going to consult anyone about this (an everyone should) it should be one of the senior engineers involved in the design of these things. I am well aware that it does not ruin the engine - it is the device used to burn of the particulates caused by the sulfur content that could have problems with the high ppm.
The only breakdown thing I have heard has been related to pick-ups (as are most of all these reports we hear) when they go into "limp mode" and cannot exceed 5mph or so. I have not idea what might happen to a larger Cummins engine over time.
