We just bought a 2015 Ram 2500 4x4 for our business. Had to search all over to find one with a pull lever for 4x4. Most now use the electronic knob. After I bought it I was 2 miles down the road when I couldn't find the CD player. Turned around, went back and they showed me that you actually put the cd in under the seat now. Could the Durnago RT be like this as well?
