Just bought a 2006 2500 with 5.9 and know I need to start thinking about gauges. I like the Edge Insight because I only have to mount one device instead of numerous other gauges, also a lot easier to wire in from the sounds of it. Just concerned about the downsides though, i.e. why aren't more people running them. Also, can the Insight be used with the Edge Juice down the road?
