Cummins 6.7 vs 5.9 please read my case..

Please I would like to read opinions on this::
This is the case::
I will buy a 3500 dually truck and will be used to go to mexico very often, once there this is the problem.. Apparently from 2007 diesel engines have come with new regulations for emissions and are designed to be used just with low sulfur diesel.
My 2 options are::
1) 2006 5.9 SLT megacab with 32k miles.
2) 2009 6.7 LARAMIE megacab with 72k miles

In mexico there is not low sulfur in market.
If all this is true, the 2009 6.7 would not be able to use mexican diesel fuel unless emissions system would be deleted, another option would be to get an extra tank that allow the truck go to delivery the load and come back using diesel from usa.
We are talking about 2009 6.7 LARAMIE megacab with 72k miles

With 2006 5.9 this problem is not active.
Since emissions system allows you to use either one diesel from MX or USA with no problems.
Here we are talking 2006 5.9 SLT megacab with 32k miles.

So... Question is:: which one do u think it worth better?? According with year, miles, engine and specific conditions about trips to MX.

Thanks in advance for your help !
