Reassuring points
Reliability- The `GMT900` base brings a real improvement in refinement and long-distance comfort without abandoning the model's towing ability.
- The `5.3` V8 still works well in a maintained truck, with decent parts availability and widely known mechanicals.
- If the `Midgate`, adaptive suspension and four-wheel-drive system are healthy, the `Avalanche II` remains unusually versatile.
