The great thing about restroom trailers is that they are mobile and can be placed almost anywhere. There are a few things we want to avoid when placing, or parking a restroom trailer. First, restroom trailers are not allowed to be placed on public streets, alleys, or sidewalks without approval or permission from the local municipality or authority. Second, mobile bathroom trailers are very heavy, especially when the tank is full of water and/or waste. So we make sure the landing surface is either paved or compacted.
