My wife and I are considering getting back to a dedicated tow vehicle/family hauler and getting a car for her DD. Looking at '03-06 Burbs and curious how to tell if the truck has the factory tow package with the 3.73 gears. The internets seem to say there is a 3.42 gear ratio and 3.73. Do all burbs have the tow/haul button on the shifter?
Thanks
