This 600-gallon aluminum slide-in unit from Pik Rite is designed for equalized weight distribution. At 51 inches in diameter, it has a 400-gallon freshwater and 200-gallon wastewater configuration. The Jurop/Chandler PN 23 vacuum pump is powered by a Honda 8 hp electric-start engine. Thirty feet of 2-inch fill hose and a 3-inch discharge and valve assembly provides versatility for every job. Freshwater is delivered by a 12-volt electric pump. Spray-on protective liner under the hoses protects from scratches and ensures years of durability. The tank comes with customizable options, and the approximate weight is 1,030 pounds, fitting nicely inside a standard 8-foot pickup truck bed. 800/337-5975; www.pikrite.com.
