How do you level a restroom trailer on uneven grass?
We're getting married next spring on my parents' property in Charleston, SC. It's a backyard wedding with 140 guests, a tent, a band and no indoor plumbing for that many people. We're renting a restroom trailer with flushing toilets, sinks and mirrors for the day. The rental company says it must be on level ground, but our yard has a slight slope. The grass is firm but not perfectly flat. The delivery truck can pull right up to the spot. What's the actual process to level a restroom trailer on uneven grass? Do I need to build a platform or just use blocks under the wheels?
