This 42-gallon fresh water tank reaches 60 inches wide and 31 inches long but only 5¾ inches tall—a low-profile solution for RVs where under-floor height is at a premium. Single-piece roto-molded white polyethylene with spin-welded connection points creates a strong, seamless vessel for potable water that resists leaks and impact.
