Place stabilizing jacks underneath the trailer at even intervals. Make sure there is one stabilizing jack at each corner and at least one at the center of each side. The more jacks you use, the more stable the trailer will be.
For use on soft ground, place wooden blocks underneath the stabilizing jacks. The wooden blocks should be a minimum two inches by six inches. You can use larger wooden blocks to make the trailer even more stable, as the greater the surface areas of the blocks the more stability is achieved.
Insert a king pin stabilizer tripod underneath the fifth wheel if your trailer has a fifth wheel. Place the kingpin tripod underneath the pin and crank it upward until it touches and supports the kingpin.
Place a six-ton hydraulic bottle jack under the leaf spring mounting bracket of the suspension. Make sure you do this with at least two brackets. The brackets should be located in opposing corners, such as the right rear corner and the left front corner. Jack up the brackets about two inches. This will remove weight from the suspension system, which greatly reduces any movement.
