Perhaps because they are so common and such an integral part of our industrial lives, the evolution of logging trucks has largely gone unnoticed. The arch bar truck is but one of many variations of logging trucks that have served the forest industry.

This N.O. series Mack truck was built in 1943 originally to haul US Army 155mm artillery field guns in Italy during WWII. It is one of four purchased in 1953 by Carl Rustad to be converted for use in logging by adding an arch and winch to the rear suspension.

It is a six-wheel drive and was converted to a Cummins six-cylinder diesel engine in 1956. It could pull 6000-7000 board feet of logs into the bush mills from very great distances and over roads of very low quality.
