Needs some help with a question.
My R/T is equiped with the Trailer Tow Group which includes "Severe-Duty Engine Cooling". This appears, according to the Magnum spec sheet, to be different than the standard in the R/T "heavy duty cooling".
Does anyone know if this is in fact a larger radiator? or exactly what the difference would be between heavy duty and severe duty?

I did a search and could not find this addressed.
