3.42's and auto transmission here as well. I admit that I haven't towed a whole lot yet, but I would definetly get it again. my mileage keeps getting better (which would be the case with all diesels as they break in). I think that the real advantage in mileage will be for empty driving. This thing will cruise really nice empty and with a load in the bed. But to each their own.......

I plan to....35K miles and going strong.

I doubt I'll have much trouble, my old 12v with 3.55's and towing like this has better than 375K miles, and I run my 2010 a whole lot easier than the 95!

Glad you like 4.10's and listening to your engine scream at you for no reason. 4.10's are gasser gears!
