DLH62C (sorry don't know your name), thanks for the link. I had seen that but it was an Australian company, just was wondering if there was any USA based companies considering the Ford/Dodge deletes I mentioned above. As far as planning the trip, well we are 6 years into a 7 year sailing circumnavigation. One more ocean to cross (Atlantic) this coming winter to close the loop. After all this water we want to try the same thing but on land and have spent considerable time planning this. Just need to finish up this sailing and find the right RV.
As I said, you'd be better off spending your time and money trying to figure out a way to travel the world with one.
If I were to travel the world today with a DPF equipped vehicle, I'd try and source a DPF assembly that was serviceable. There are companies out there that make them. What does them in, is ash build up from the combustion process. Its important to use oil that meets low ash specification CJ-4.
I assisted a Swiss couple via FB stranded in Mexico derailed with a plugged DPF on a Defender. When the DPF was cut open it was packed full of ash. When asked what oil he was using, his response was , "Good quality, top, top". He didn't know if the oils he had been using ever met low ash specification or not.
