This review is of a model of a Mack Titan Tri-axle. 

It is in the colours of Thomas F Corbett.

Packaging

It comes in an outer shipping carton which encloses a Mack branded box.  The model is held within a pair of factory sealed trays. 

There were no missing parts or defects on the review model.

Included is a plastic pointer and a bag containing spare mirrors is a thoughtful touch. Another accessory bag is also part of the package.

There is no information about the real truck but a simple instruction sheet describes the lift axle functionality of the model.

Detail

The chassis is very detailed including the drive train, and hoses run to the rear axles.  The tyres have a good tread pattern but there is no branding in the side walls. The wheels are very detailed and look smart.

On top of the very fine front grille is a silver bulldog mascot, and a high point of the model is the artwork decoration on the hood and doors which is exquisite.  There are also additional mirrors on the hood. 

Under the hood the engine is impressive being made up of a number of different parts.

The cab roof has air horns and lights. There is a very thin aerial and chrome mirrors.  The interior is highly detailed.  Outside the cab are textured steps and the exhaust stacks have decent looking holes.  The various tanks are detailed and some filler caps are highlighted.

Behind the cab there is an excellent chrome cabinet tower with a beacon light array on top.  There are lines for connection to a trailer and excellent non-slip walking surfaces.  At the rear there are lights and various towing hitches can be fitted.

A metal towing bar is also included as an accessory along with an oversize load sign and fabric flags.

Features

The front wheels steer, with the steering achieving a very good range of movement.  There is working sprung suspension on all axles.

The lift axle can be raised out of service.

The hood opens to reveal the detailed engine. 

The cab doors can be opened to a 45 degree angle. 

The fifth wheel has a spring loaded lever to secure a trailer in position.  It can also be adjusted longitudinally.

Different towing hitches can be fitted front and rear, and an oversize load sign and flags can be added.

Quality

This is high quality model, with a high metal content. 

The paint work and artwork is top notch.

Price

It is a premium priced model of very high quality. 

Overall

This Mack Titan model continues Heavy Haul Replicas lineup of very high quality haulage models.  The artwork is outstanding and the customised parts make for an accurate replica.   It pairs well with a Heavy Haul Replicas Rogers Beam Trailer.
