The story of the model
DX3 history
The earliest DX3 brochure found is for the 2013 model year. In March 2018 RV PRO reported that the DX3 was built on the Freightliner M2 106 chassis, with prices starting at $299,000. The 2019 and 2020 brochures list a 350-horsepower Cummins 8.9-liter ISL engine with 1,000 lb-ft of torque and four floorplans from 36 feet 8 inches to 40 feet 9 inches.
The 2027 model is listed with a 360-horsepower Cummins L9 engine with 1,150 lb-ft of torque on the M2 106 Plus chassis. A shorter 32KD floorplan, at 33 feet 10 inches, is the lowest-priced model in the line.
