2006 Dodge Ram 2500 Cummins Mega Cab

2006 5.9 megacab Laramie with 173k miles. Never tuned. Has Banks air intake, 4in full MBRP exhaust, business (full) console, leather heated seats. I have full front end MOOG rebuild kit that will go with. Haven't put it on because it doesn't need it yet. Had the entire underside dry ice blasted and coated about a year ago and has 3 year warranty for that service. Tires have about 5k miles on them. Just installed the upgraded Custom Battery Cables brand complete kit this week. Batteries new about a month ago as well. Only selling due to camper being sold and it will just sit. Asking 18,000 but these are all over the place for price so willing to go down a smidge and will take monetary donations above if offered!
