Used primarily for towing my KZ-RV Frontier 2505, purchased at a reduced price due to rear dually locking up on turns. First owner advised me to change fluids which did not help. GMPP warranty found the problem in the PIG Head and replaced no problems in the past 50 thousand miles. Excellent tow vehicle and will replace with another Silverado in the future.
If you are looking for fuel economy, this may not be your vehicle. Most of my trips are less that 5 miles and MPG range from 9-11 MPG. We have pulled a fifth-wheel trailer with 10,000# of dryywall on it. No problem! I have replaced and battery and alternator. Hood release also broke on inside (the plastic pull). I as very glad that the truck has been as dependable as it has been as the dealership service sucked! I think that they did manage to get the power door locks and security alarm installed by a vender but they never fixed the windshield leak or finished preping the vehicle for delivery!
