Remember that new truck that I converted to a dualley and took racing seen a couple of film strips ago? It had problems. The Duramax was great but it had a fatal flaw. Without warning it would be totally dead when I went out to start it. The dealer couldn't find the problem over the 6 years I had it. Soooo, we replaced it with this new Duramax by GMC. Wish I could have gotten in on the lemon law. Grrrrr.
