About the Truck

A true standout of classic Mack restoration, “Summer Lee” is an exceptional B61 Mack that has undergone an incredible 11-year full restoration by owners John and Vicki Bock.

Powered by a 285 Cool Power engine, backed by a Mack Quad gearbox and Mack diffs riding on Neway airbag suspension, “Summer Lee” combines old-school Mack toughness with modern comfort and drivability.

The cab itself has also been mounted on airbags and features several modern upgrades including:

• Air Conditioning
• Power Steering
• Cruise Control

Every aspect of this truck reflects the dedication, craftsmanship, and attention to detail invested throughout the restoration journey. From its immaculate presentation to its engineering upgrades, “Summer Lee” is a perfect example of preserving Mack heritage while making the truck enjoyable to drive today.

Travelling from Central Queensland to support the Queensland Mack Muster, John and Vicki’s commitment to both the trucking industry and the Mack community is greatly appreciated.

Queensland Mack Muster is proud to welcome “Summer Lee” to this year’s event and convoy celebrations — a truck that truly honours the legacy of the legendary B61 Mack.
