Your getting a dually for weight, or else you would be getting a SRW. 4.10's are for weight, everything else is a compromise.

My exact thinking, have no desire to see how fast I can come off a stop light,3:42 gears will do just fine with the power of the new cummins

It's not about coming off the light fast, it's about the 20% more torque you get to the rear wheels with 4.10's than 3.42's for the same engine output.

It's less stress on the trans and engine for the same power to the ground. For 3.42's or 3.73's to put the same power to the ground (where you need it) the trans has to drop a gear to get the torque multiplication, more heat/stress in 1 place instead of spreading it out.

I have reader into your responses that you have never driven a diesel truck. The low end tourque is awesome! With my old 5.9 even in low speed city driving I very self ome need to shift.

Yes low end torque is awesome, maybe it's where I live/tow but there are many times I wish my 05 had 4.10's winding up a 6-8% grade at 4-8K feet. 3.73's are a good all around gear, but the extra 10% at low speed is very helpful. That's with more hp/tq than the newest 6.7 makes...

Many people thing Dodge made a mistake only offering 3.42's in the SRW trucks, when towing heavy it compleatly negates the 6th gear. Why build a truck that won't use it's top gear towing? If you want to make 3.42's the norm then trade the extra OD for a gear in the middle with a lower 1st.

Again, probably because I never tow on level ground.

I never had problem, never knocked out a tranny ,never blew a motor with 3:73's , with an old ford 7.3. Now you are telling me I am going to ruin things with this new cummins, thats pretty funny completely negates 6th gear, I know several guys towing heavy with 3:31 ,and never getting out of 6th unless pulling the mountains, and you think that cummins with 3:42 are going to be any different. The ford running @ 70 was right at 2000 RPM pulling in the top gear fourth, this cummins without really checking it yet is going to be pretty close to the same RPM in sixth gear @ the same speed, and with nearly double the torque ,and horsepower .
