My wife ordered a new Ram on Saturday, too... 3500 CC LB DRW 68RFE 4wd 3.73 Air suspension. It should be awesome with her 14k gvw 5er and she'll have room for more, later. The dealer had one on the lot with Aisin/4.10... it sure was tempting but I already have a keeper! Craig
She will spend the money for rear air and NOT the tranny upgrade. Makes little sense to me! She should have gone for the 4:10/Aisin!

You beat me to it!
I have owned both trans. The 68 did the job but the Aisin does it MUCH better with the lower starting gears and the more solid shift points. Oh also the extra HP and TQ are nice!
I have said it before the 3.73's based on personal experience are not needed. My 11 HO with3.42's and 68 towed 28-29K combined, the only issue was starting on a grade. I towed in 5th the exact same rpm's as the 4.10's in 6th. Example 1,750 @ 60. If ordering a RAM Dually and I knew for a fact I would never exceed around 27K combined I would get the Aisin with 3.42's any more weight then 4.10's and Aisin.
C Shomer you will love the factory rear air ride!!! I would Seriously consider changing to the Aisin!
