The 20,000 TB is great for you customers who do alot of equipment hauling but still need a truck short enough to get into the city to tow a car or pickup truck. The deck lengths range for 18ft to 30ft this unit goes great with a single axle chassis with a tag or pusher axle. The tag would allow you to legally haul 20,000 on the bed for things like small machines and multiple scissor lifts.
