A 3500 DRW Aisin with the 3.73 will give me a well built...overbuilt tow capacity of about 24,000 lbs. About 4,000 lbs more than an Aisin with 3.42 gears. And yes I know my 2500 is a little short on the tongue capacity... Hauling her empty right now less than 35 miles. I do have air bags on the 2500 which helps keep the front tires from feeling light. Any and all wisdom and experience is welcome...kind of want to know the RPM’s are at 65 hauling and running empty?
Thank you guys

Our 2014 RAM Long Horn Edition came with the 3.73 and Aisen tranny. It pulled our 16,000+# Big Sky great.

I have 4:10 gears, @65 she it right at 1800 rpms. We went to north Arkansas over Labor Day which was a 1200 mile round trip and we averaged 10.6 mpg. Had a few areas were we kicked up to 70 to pass big trucks and traffic.

Check the GWVR and max towing weight of your proposed TV. My '17 GMC varies a lot based on the rear-end ratio. I run a 4.56 and am rated to tow 17,000lbs. A 4.11 rear-end drops that to 15,000lbs and a 3.4 drops it even more. You get the picture.

I'd go with 3.73, although a new 1 ton truck should handle the load either way. For resale purposes, or if in doubt, I like 3.73 better.

He is probably referring to the SWR, which is only available in 3:42 , Aisin or not, DRW you have the option of all three. The Megacab 3500 DRW which is what the OP is buying, only Ram with a short bed, but also has the three gear ratio as options.
The Aisin has nothing to do with whats available on the SRW ,its only the 3:42

You are correct ,that window sticker is a DRW long bed crew cab, 3:42 as said is the only one available in the SRW 6.7 Cummins ,Aisin or the 68RFE.

I am towing with the same truck ,except SRW. 2014 Megacab 3500 3:42 gears 68RFE transmission ,not the Aisin.
Here's your advantage with 3:42 gears , and the Aisin over MY truck. First its got more torque ,and horsepower. But the BIG think, which IMO makes the Aisin a better option then the 68RFE, is the first two gears are lower, gets those heavy loads moving easier.
My fifth wheel is right around 13,500. Those 3:42 gears do great with the 68RFE, no complaints. I can't imagine needing anything else with my weight. Pretty sure you would be happy with that Megacab 3500 DRW, with 3:42 gears

Surprised you are not happy with 3:42, having the same truck, but with the 68RFE, mine tows 13,500 great. I would think that 3160 is in that same weight range . You having those two lower gears in the Aisin, I can't see where you would have a complaint, maybe you could elaborate on needing 3:73

3:42 in my 13 Ram 3500
For 6 years I pulled a Montana 3400RL with a Cummins diesel in a '13 3500, with weights around 13-14K. Not a single regret. Ever.

No it was an option on the 2017 also. I have the 3.73 in my 3500 Dually and have to agree with others it it a good all around gear set for pulling and when you are not. Very happy with the way it handles the trailer

I just returned home from Branson to Houston and i have the ram 3500 drw with 373 gears and 68rfe transmission. Hiway 65 from Harrison to Conway Arkansas is very hilly and my truck pulled my 16,200 pound trailer very well. I've traveled the O'zarks, Smokies, and Rockies and i have no complaints with how well my truck pulls the rv. I usually travel at 70mph and i got 10.3 mpg coming home from Branson. I got 7.3 mpg from home to New Mexico but i was bucking a lot of wind. The Aisan with 342's is rated to pull more than the rfe68 with 373's so either would be great. If rfe 68 then i would go the 373's.

I have a 2011 Dodge 3500 diesel dually with 4:10 gears and a 2016 RAM diesel 2500 with 3:73 gears they both do a great job pulling my 2012 Monty 3625RL but I prefer the 2016 for long trips because it uses less fuel

Of course if you have other criteria to meet on TV length then perhaps the short bed is the solution you need unless you are getting a Mega Cab which is the same length as a crew cab with an 8 foot bed.

Thank you all, I did end up getting a LB and can really see the benefit especially when full timing. Added a tool box already and still have lots of room, crucial when full timing. I don’t think I could of gotten a better TV. It is simply awesome!
Thankful, Dirk

I don't really have a complaint. I would just just like to not have a wide gear difference in the higher gears. That is more of a transmission gearing issue but a higher rear would help out a bit. Plus, that gearing would make towing in sixth a bit easier.
