Re: Mileage?

I read somewhere that those with 4:11 axles get in the mid teens, but pull trailers better. Those with 3.73 axles get in the high teens to low 20's sometimes, but suffer in the towing ability.

Guess it is hard to have it both ways -- but I'm wondering about the new ones with the 6-speed automatics. Supposedly it is a double overdrive which might give both advantages. I dunno!
