I have a 2003 HO 4x4 quad cab 2500 Laramie 48re automatic. I am considering doing a power upgrade. I pull a 10,000 pound fifth wheel. Does anyone have this same setup or close to it? If so have you done any power upgrades? If you have, what type of upgrade (or grades) did you go with? Was their a noticeable difference in power. Any advice with my set up is welcomed. Thanks.
