The Cross Country 303QR4E is a tridem quarter frame end dump built on the 4-inch one-piece radius body, published by Cross Country as a 34'10" tridem quarter frame unit with a 30-foot box. It combines high tridem payload with the tight-quarters unloading stability that defines the quarter frame platform. Hardox 450 body plate and a 100,000 psi hi-tensile top sill give it the durability for continuous aggregate and asphalt work.
