Final Verdict: Is the 2015 GMC Sierra 2500HD a Good Pickup Truck?
The 2015 GMC Sierra 2500HD is ideal for those needing a powerful and capable truck for towing and hauling, especially those who value a comfortable ride. It's worth buying if you find a well-maintained example with a good service history. A used model is a good value, but be sure to inspect it thoroughly for rust and DEF system issues (if diesel). The SLT or Denali trims offer the best combination of features and comfort. Avoid neglected examples, and prioritize models with documented maintenance. If heavy towing is a must, the diesel is worth the premium, but be prepared for higher maintenance costs.
