LS 22 Knaack Job Box v1.0.0.0
This job box is in the Miscellaneous section, and has the same service function as the FST99 from GtX.
There are three attacher joints by default, semitrailer, semitrailerCar, and implement, so it can attach to a variety of vehicles, but you can also strap it down, or leave it in the corner of your shop and use as a stationary service trigger.
