Wrong Axle Ratio Ordered
I was reviewing my order confirmation sheet (slow day at work) and found that my dealer put in X31, 3.31 Reg Axle instead of the X3J, 3.55 ratio.
I know I'll get better MPG out of the 3.31 but I'm going to be pulling an 11k gross bumper pull trailer through the mountains. Maybe I'll move up to a heaver trailer some day too. How big a deal is this going to be? I'm going to call my dealer and see if it can be updated, but I already have a build date that is less than 2 weeks away.

My buddy took a truck off the lot that had a 3.31 rear end and he has come to regret it. We have similar heavy trailers (19K) and he gets 8 mpg regularly. I always got 10.4ish when I towed. We ran exact same tires (Toyo MT 315/60/20) and the only difference between our trucks was that he had 10 inch wheels and the wide fender flares. We both figured that the main reason for the difference in mileage was due to the rear end. He couldn't stay in 6th gear when I could. If you stay with the factory tires it's less of a concern as larger tires will exacerbate the taller rear end.

I handed the dealer my list of options. He entered them. I reviewed the order, but missed the axle ratio. I signed the order sheet. I'm as culpable as he is. If this was a difference between 3.31 and 4.30 I would be willing to give up my $1,000 deposit. I can live with 3.31 and hopefully the truck will be so great that I'll forget about the axle ratio completely.
