Someone out there with a '07. 5 3500 SWR Quad Cab Long Bed w/ 6. 7 Diesel and 6 speed automatic w/ 4. 10, tow package... what is the GVWR? Is it 10,100 lbs? The reason I ask is that Oregon DOT when it comes to chain and traction tire requirements uses 10,000 GVWR (when not towing) as the determining factor for some of its traction tire laws. I would venture to guess as long as a person was in a 'single' rear tired light truck there wouldn't be much of a chance of being checked for that extra 100 lbs anyway... dual rear tires though would likely raise the red flag.
