My truck is a Stalick International 4700. It has the 300
horsepower 840 pounds of torque 530 cubic inch engine, an
Allison 3060 six speed transmission and 4.44 differential
gears.
I have added Mor-Ryde front suspension and a Trailer Saver
air ride hitch.
I pull a pounds 40 foot Travel Supreme weighing
about 18,5000 pounds.
