1/25th scale Dodge Ram?

Any one know if there is a model containing the Rams diesel from Cummins? I'd like to build one of the Rams "VTS" models into a duallie, with a Cummins but....Finding what I need to do it might be the trick! I have the Duallie bed, I just need to get a Diesel engine! Might prove difficult!

Anyone know of anything that suffice as a diesel for a Ram?
