How do you level a restroom trailer on a sloped festival field?

A restroom trailer must be leveled using its built-in stabilizing jacks and often requires additional support from cribbing blocks on a slope. The rental company will typically handle the leveling during delivery, but you need to prepare the site. Confirm the trailer has its built-in jacks, which are turned down to take the weight off the wheels. On your sloped field, you will likely need to place solid plastic or wood cribbing blocks under the jacks on the low side to achieve a level position. The driver will use a bubble level on the trailer frame to check for level side-to-side and front-to-back. The doors must open and close easily, and the toilets must flush without pooling water. Your one-foot drop over 40 feet is a manageable 2.5 percent grade. If the slope were steeper, you would need to find a flatter area because excessive cribbing can become unstable. Ensure the spot has firm ground and clear access for the delivery truck and the vacuum truck that will service it.
