Default Replacement of 2005 Express 3500 6 liter radiator

After 175,000 miles I think it is time to replace the radiator and hoses. I haul a 29 foot race car trailer.
should I upgrade to the larger aluminum radiator?
thanks,
Jack

After a good deal of telephone calls and due diligence I believe a good solution for an upgrade is the Mishimoto MMRAD-GMT-99.

It is an all aluminum 4 row with ports for the trans cooler lines and the oil cooler lines. Not inexpensive at $633, but worth every penny!
