Frontier, Vertex, & Summit Measurement Guide

Please refer to the measurement guide image provided. The required dimensions are:

• Measurement A – Interior bed length from the top edge of the front bulkhead to the top edge of the tailgate

• Measurement B – Interior width between the bed rails at the front (cab side)

• Measurement C – Interior width between the bed rails at the rear (tailgate side)

• Measurement D – Width of the front bed rail

• Measurement E – Width of the bulkhead (measure the narrowest point if it tapers)

• Measurement F – Width of the tailgate at its narrowest point (typically near the bed sides on contoured tailgates)

• Measurement G – Height from the top of the bulkhead to the highest point on the cab (including antennas; we recommend removing screw-in antennas for accuracy)
