I'm with Barrett (architect-builder) re. "cold blooded." I've got an '04 6L and she is very sluggish while warming up. They're designed that way to keep from hurting a cold diesel engine. But after she warms up, look out! I love my PSD!!! Mine had 24k miles when I bought it. I now have 56k (tow a 5th wheel) and I have no complaints. When she warms up, she'll kick some serious butt!!!
