4:10 or 3:73 ?
Possible upgrading to Ram dually. I'm pulling 12,500# gvw with SRW and 3.42 rear end. Usually lock 6th gear out. Plan is to move up to new 15,000# gvw 5th. Not sure if I want to get 4.10 or 3:73. Wh...

Why trade. We tow a 16K 5th wheel with a SRW and 3:42's work great. Chris
I agree with this. You already have enough truck. And I'm not sure why you are locking out 6th with your current trailer. Sure isn't necessary.
As for your question, I have 4.10s. And I wouldn't buy them again. Just don't need them with the new trucks - plenty of power, don't really need the low gears.
60MPH is 1750 RPM with 3:42's. My Austin will not shift to 6th in T/H until 65 MPH, and I do not tow that fast normally.
It is all related to the tall gears using it the way RAM designed. Chris
Well, my truck has the 68RFE not Aisin (I assume auto correct gave you Austin above), and I rarely tow below 65 MPH. I guess in your situation you might lock out 6th (although I still wouldn't). I think the Aisin with 3.42 would tow very nicely at 65-70.
