I do but 5th is geared so much taller than 4th. 60 in 4th is hitting 3K, shift to 5th and you're now at 2K.....just a pretty big drop. Guess I'm just spoiled by my sportbikes...very close ratio 6spds.

I got about 18.5 mpg my last tank in mixed driving. I average about 80 on the freeway.

4.10s are great on the hwy. My daily commute is from Escondido to North Island. At 70 MPH I am just under 2500 RPMS and at 80 I am just under 2900. My Avg MPG ranges anywhere form 19 to about 20.5. On the 15 I drive anywhere from 75-85.

5th gear is where I'd go. Like I said before I guess the trade off between the performance and mpg would just cost me a few mph's at cruise.

I've had the 4.10s for about 2 years. It did take some getting used to as a daily driver, cause I'd be in 5th sooner, but I love them and haven't looked back. FWIW I get average 19.5 to 20.5 every tank with about 70% of my driving being on I-4 and I-275 in Tampa. At 75-80 I'm in the 2800 rpm range.
