Omega J-Series restroom trailers from AMS Global have a Jets Vacuumerator system that liquefies waste and paper products and can pump to a sewer up to 100 yards away. They flush using a pint of water, so onboard waste tanks will hold more flushes. Frame walls are built using 1.5-inch tubular steel with durable granitized steel floors. The trailer is constructed of steel, composite fiberglass panels and aluminum. The chassis has been tested at over 16,000 pounds capacity and incorporates four 4,000-pound-lift remote-controlled jacks that reduce liability issues and achieve ADA compliance. 888/574-4222; www.amsglobal.us.
