Zwight Logging of Yakima Washington owned a Berger Marc-V swing yarder on rubber and logged with it for many years.
In June of 1987, the Berger upper was pulled off and a new Thunderbird TSY-255 (Serial Number S-5080) was mounted onto
the Berger 4-axle carrier. Shown here we see the machine in travel mode with the gooseneck/boom stand on the front and
a two-axle booster on the rear. The steering tires come off when a tractor is hooked up on front for longer and highway moves.
