The 2001 is a very reliable long lasting vehicle. Many people would say they are great for everything. The 7.3 liter turbo desiel engine puts out a good 275 hp stock out of the factory, which can be changed by just buying a $300 Chip tuner. This tuner can download many tunes that can add hp, help with gas mileage, and add with torque for towing. The downside with the 7.3l engine is that their is a chance that you might get one where the engine block will melt. The 7.3l litterly have melted, other than that the 7.3l ford powerstroke is a great fast high powered truck.
