Looking to buy a used KR dually 6.7l, I can find nice ones with 120-150k in my price range, most are 2011 or 2012s, other than I know the 15 s have better turbo and fuel system, are there any reasons not to buy an 11, 12, 13 or 14? What should I be Leary of, and be looking out for? I will probably eventually upgrade turbo and all, truck is primarily going to be used to tow a heavy 5er, 16500lbs GVW, and 12800lbs unloaded
