These quality mobile wash systems prove to be at the top of their class. There are three trailer models and two slide-in frame designs to choose from in this series of mobile wash systems. Each trailer is constructed of heavy wall steel tube frame utilizing sealed beam lights with the wiring inside the tube frame to reduce exposure to the elements that cause premature light failures. The POD system provides a convenient system that like the Entrepreneur IV allows for use with or without your water supply & POD slide in frame assembly.
