The Flat Vacuum Tank from Crescent Tank Mfg. meets multiple equipment needs with one truck. A tank can be installed as the flatbed to carry restrooms, and allow the vehicle to tow trailers. Tanks hold up to 350 gallons of freshwater and up to 1,000 gallons of waste, carry anything on the bed, and can be custom designed with multiple storage options for products needed at events. All tank trucks have a low profile and inconspicuous design for attractive special event use. Several sizes are available, with the largest able to carry eight restrooms on the deck and two on the liftgate. 585/657-4104; www.crescent-tank.com.
