kurt-trucks:Spotter trucks. These are used to move trailers around a lot (or yard), either for maintainence, like these, or at warehouses where they put them in and out of dock doors. Hydraulics lift the fifth wheel to the trailer, so landing gear on the trailer doesn’t have to be raised and lowered. When driven by cretins and dropped loaded and rolling, landing gear on the trailer gets damaged. Tires get flat spotted as well when brakes don’t release and they drag the trailer anyways. Two things to check for. YARD JOCKEY!!! -- source link
