I had Red Top Optimas in my 97 and they were fantastic and are still going strong in the truck as far as I know. I think they were the "original" Optimas, before manufacturing changed hands. I now run a set of the Diehard P2's in my 2004.5 and they are only 2-1/2 years old, but are doing fine and are showing now outward signs of failure. The diehards are pricey, so wait til they are on sale, but I wouldn't hesitate to buy them again.
