Guys, just curious pros and cons if 2 trucks. I currently own a 2x4 4 door 2006 3/4 ton duramax that I love, BUT an opportunity has came up and I m looking at my dream truck 2011 1ton single wheel 4 door 4x4 with LOW miles. Just want y'all's opinions this truck has the dsp and the environmental exhaust. My truck does not. What would y'all do? Stay with ole faithful or upgrade?
