That chart for the '07 doesn't cover my '08 mega. I have a 4wd, auto 3.73 non-dully. I have owned for 6 month. I go out today to shop for a 5th wheel and everything I want is around 13,500 dry. So I check my sticker and it says 10,100#. Give me a break. So I check my sales brochure and it says 10,500. Dealers are scratching their heads too. Somebody sold me a bill of goods. Hell this tows less than my old 2000 cummins. So not only do I have a dinasaur that gets lousy mileage I have a tinker toy that won't tow squat. What a crock. Should have bought an rv and watched that depreciate instead of this.
