2012 Silverado 2500HD, really like ours, it works great! Was easy to dial in, now I just plug the trailer in and its set. No worries. Also with the Tow-Haul mode it makes trailering very easy and comfortable. I know my truck is four years old already and i am surprised at the advancements in technology it has compared to my last truck (2004). I can only imagine how nice the new trucks are with built in rear view cameras, proximity alarms, lane and side views etc..
I ran the Prodigy II brake control and was amazed how advanced it was compared to the older brake controllers I have used in the past..
Looking forward to what the future brings on my next truck!!
