The stock may work ok but from my experience a 3 or 4 row would be much better. Had too many 2 rows and had them get hot especially in the summer. My van conversion has a 3 row I think but the truck will get a 4 with a new midly built six with a/c and 4x4. If you use the stock one, get some Redline or Prestone Water wetter or whatever the Prestone brand says. Its a cooling anti freeze enhancer and I have used them both they really work. The stores sell tons of it here each summer. Can hardly keep it on the shelf. You should put in 2 bottles. It gets very hot here in the summer. Tripple digit temps and using a/c its really helps keep things from over heating! Keep it cool! Henry
