Well, after reading the latest TDR it does appear that the Ram will be using the SCR system starting in Jan 2013. If that is the case I will be waiting a little while longer to get the SCR system. I know a lot of people don't want the urea tank and something else to have to fill, but I think it will be the best alternative to achieve better fuel economy, and hopefully less regenerations and less fuel dilution as well. I just hope that Dodge puts the tank in a better place than GM did with that ugly thing hanging under the truck. Can't believe they did that. So, I'm looking forward to that and will buy the Dodge Cummins if that happens as planed.
