Well if your reading my posts and not jumping over to look at what contractors are posting,
I'm a 52 year truck mechanic. That Mack is about as tried & true as it gets, the 673 was
Macks mainstream bullet proof power plant, The gear box is a RTLO 14618 Eaton-tons of
gears, Hendrickson walking beam probably 46,000 lb suspension, Mack rear drives, real tough.
The front axle will be more than enough with those tires. Parts for this truck can easily be had.
