I don't know a whole lot about the actual "Night Runner" package price differences, but I know that the NR was available on durangos, rams and srt rams among a few others. As far as SRT's, there were only 114 Night runner quad cabs total, and only 79 Night Runner reg cabs made. The nameplates say /400 but there were not 400 made. My truck says that it is 384/400.
As far as selling, I have been thinking about it. Only because I have 5 vehicles to myself...which is kind of rediculous but until I HAVE to sell it or I get a great offer.....I will probably keep it.
