The WorkMate portable restroom service truck from FMI Truck Sales & Service has sidewinder tanks with consistent equal-weight distribution, designed to extend brake life and improve handling. Two food-grade poly water tanks are plumbed to provide brine, freshwater, premix or any combination of fluids with no corrosion or rusty water. The ergonomic workstation has more than 60 cubic feet of storage to minimize restocking and driver movement. It can carry four restrooms on the bed, and the modular design allows components to be easily replaced or transferred if damaged. The vacuum system is plumbed using hot-tar hose and Masport components. Marine-style wiring is used, and all electrical systems are contained in a watertight panel with automatic-reset circuit breakers. Each system is color-coded and individually loomed. 800/927-8750; www.fmitrucks.com.
