Had a crack on a cabinet underside. Used the 12T bottle jack to support it while the glue dried.
Bent the tailgate by hitting the kingpin. Used a combination of lumber, bottle jack & weight of the trailer kingpin to straighten the tailgate back pretty close to new.
Got stuck on a wet hayfield at Oskosh Air Adventure. Used lumber & bottle jack to lift rear of the truck, with trailer, & slide boards under rear wheels to have traction & get on firm ground.
Actually have used the thing to lift the trailer for wheel rotation, shock changes, brake drum changes, spring stack changes, anything else that I can find a use for it.
