I am looking to buy a 4 door 2001 or 2002 4x4 truck. I am undecided between the Sierra 2500HD Duramax, Ford F250 Super Duty or Dodge 2500. The truck will be used by both myself and my wife as a family car and sometimes to pull our 32 foot travel trailer. I have decided I want a Diesel motor. I like the look of the Ford F250 Super Duty, but have been hearing about some problems with the diesel motor. We live in California so snow and freezing temps are not a problem. I'd appeciate any input anyone can give me!!!!!!
