Recreate a distinctive piece of North American fire apparatus with the MOC-254378 Pierce Arrow XT Tiller Fire Truck Building Blocks Set. Designed and authorized by Silver Ridge, this 1,889-piece model is based on Southern Marin Fire District Truck 4, a 2018 Pierce Arrow XT tiller truck equipped with a 107-foot Ascendant aerial ladder.

The model captures the defining feature of a tiller truck: its long articulated tractor-and-trailer layout. The front cab and rear aerial section connect through a fifth-wheel mounting system, allowing the two sections to articulate naturally and also be detached for separate display.

Functional details include a 360° rotating aerial ladder, deployable outriggers, detailed roll-up equipment compartments, and a fully developed crew cab. A dedicated sticker sheet is included, adding vehicle markings and finishing details to the completed model.

From the Designer

Silver Ridge created MOC-254378 as a recreation of Southern Marin Truck 4, a 2018 Pierce Arrow XT tiller truck stationed in Mill Valley, California.

The design focuses on the features that make tiller apparatus unique: the articulated chassis, fifth-wheel connection, long aerial ladder, stabilization system, extensive equipment storage, and multi-seat crew cab. The rear ladder can rotate fully, while the tractor and trailer can be separated for closer inspection or display.
