Diamond 3500
Davey Coach now offers one of the largest true composite buses in North America. This unique co-pilot design reflects the innovation needed to deliver larger charter-style layouts on a medium-duty chassis.
What sets a Diamond F-Series build apart is its commitment to higher standards across the board—featuring a weight-optimized design, lower entry step height, increased interior headroom, and an enhanced passenger environment. With a lowered floor frame and expanded aisle space, every detail is engineered to maximize comfort at each seating position.
