Let start by saying I was in the auto repair business for over 30 years. All the trucks on the market are pretty well made. Each has It,st own problems. Some are fixable some not. If the problem is a major engineering problem, it might not get fixed by the dealer. Dealers fix minor problems quit well. You have to check with previous owners of the model you are interested in to see if you can live with what ever problem it might have. Check major features of each vehicle such as 4 valve er cylinder motors, 6 speed trans variable valve timing, and 8/4 cylinder operation. You have to decid wheather or not you think a company can put the reliableity you need in each of these or other features. trailer towing ratings, rear axle ratios,brake sizes all are apart of purchasing a truck. Think about what you are going to do with the vehicle and then make your decision. My best deals have been made with the Fleet sales person, ask for him when you walk in the door. End of the year rebates can be a good deal. Also check with your mechanic to see what one he works on the least.
