I performed a search on this subject and couldn't find a clear answer. I want to know if I would be sacrificing towing capabilities with 3.73 gears. I am thinking of trading my current 2WD dually with 4.10 gears in for a 4x4 dually with 3.73 gears. What would the upside and downside be? Both vehicles will be 08's. Thanks for your advice in advance.
