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 Aisin 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
