The MAL slide-in series has a variety of tanks ranging from 300, 450, 550, 650, and 900 gallons with custom sizes available. The twin compartment tank holds waste water in the main tank and fresh water in the internal tank. The internal tank acts as a baffle helping to reduce the amount of sloshing making stopping and cornering easier. The lighter aluminum tank weighs significantly less than a mild or stainless steel tank, which results in less wear and tear on your truck.
