I wouldn't tow with a wrangler. The V6 is not all that powerful. It's rated to tow 3500lbs max. I'd assume that's in a Rubicon with the 4.10 gear ratio. The 3.73 may still be rated at 3500lb, I'm not sure. My wife has a 2008 wrangler with the 6sp and we like it a lot, but thinking of towing anything with it would not be particularly something I would look forward to. Definately not with the auto trans. The Jeep groups are chock full of problem with that auto even without towing. If you never hit much hills, the 6 speed would probably be ok, but not in the mountains. It takes some pretty good shifting to keep 65mph up mountain passes empty. Don't want to say it's not a good vehical, we just love the jeep, but not for towing for me at least.
