My 2 concerns buying my new 2019 Mega Cab 3/4ton Limited was that I’d have problems with the D. E. F. System and I also had the feeling that I shouldn’t get the auto leveling system. The salesman told me they weren’t having any problems with either. Even though I knew that to be incorrect. That’s on me. Both the D. E. F. system and the auto leveling systems won’t work. My truck is in limp mode and needing a back ordered part. Been over a month and keep getting new dates as to when the parts will be in. The auto leveling system compressor is whacked in cold weather. I’d recommending to move on or not get this equipment. I’ve got 6,400 miles on a vehicle that sits in a dealership lot. Not able to utilize it for what I needed it for. The dealership has offered me a loaner car. A Jeep. Hard to bull a 12,000 pound trailer with that.
