2005 Dodge Ram 2500 with a 2022 26ft Lacosta car hauler trailer. I bought the truck a year and a half ago and it was a true grandpa truck. It was completely bone stock down to the stock exhaust and air cleaner. I did put an S&B cold air intake on it because I live in the mountains where the oxygen is lower and we lose hp. Other upgrades are the radiator clutch fan adapter to fit the ford 7.3l manual clutch fan instead of the Dodge factory electronically controlled fan clutch. It threw a belt and cut the fan wires and the Ford design is a true mechanical clutch, better design. Also added a PTS pto cover that adds 2 more quarts of Redline MT85 trans fluid for smoother shifts. The only other mod I did is the gauges to monitor for trans temp, boost and EGT. No tunes ever on this truck to my knowledge, was completely stock when I bought it. Have to factory air box that will go with it. The body is straight beside the dent in the upper fender and broke mirror plastic in pics.paint is good for its age besides some chips and a few light scratches. The trailer is basically brand new. I bought it new in late 2022 to move to New Mexico, made one load from Texas, and has sat here since. Great deal on a combo, you can make money with this setup, hotshot diving or haul for your contractor business. It's a Gen 3 Cummings with a stick, doesn't get much better than that!  Want more pics or questions just ask.
