I/we bought a 2015,1500,4x4,Quad Cab,short bed Hemi a bout 8 months ago, with 11,500 miles. It has been a joy to own. I have done a lot of stuff to it. Now, I have the opertunity to get a new 2018 but I can't decide on a 1500 or a 2500. If it is a 2500, I would get the Cummins, a 1500, I would stay with the 5.7. The 2500 would be 9 inches longer and I can fit it in the garage. This truck would probably be my last brand new truck, I am 58 but maybe not my last truck. Wants and needs are a big thing, I am just having a hard time figuring out the two))))))) Help, what is a old guy to do?
