That's what I was looking at.. how did you run them? did you have the automated stuff going on or simply air them when loading them?
I ran manual, no on-board air. Really only set to 35 psi for my trailer or 5 psi unloaded. A few times to 90 to haul a pallet of landscape blocks.
If I was going to do it again, I'd get the top end wireless dual control setup. I *think* I'm better off on the SRW with the factory air just for the unloaded ride quality with the softer spring pack, but that wouldn't be a factor with a dually.

Gotcha. Looks like ill be closing the deal tomorrow. A bit of change of events, the truck will have the 68rfe with 4.10 gears AND factory airbags. What do you all think? Payload on sticker says 5375, and I should be just right there... Do yo guys think factory airbags should suffice? I wanted the AISIN with 4.10s and no airbags, but at 20+ off msrp I just couldn't say no... I should finalize tomorrow. Last minute inputs?
Your other posts say you're right at 4K with your camper. What was the payload on the SRW that you overloaded?
If you're not towing heavy the 68RFE should be fine and will probably drive smoother than the Aisin. You're the one in a pinch to get rolling so if you can't find exactly what you want, then you may have to settle. With 4.10's I hope you're not a speed demon or like filling up.
P.S. Does it have the 50 gal tank (2020?)?

Yeah, so right before i sold the truck to my buddy we went over to the scale to get weighted and i was wrong all this time. The camper alone is 4200 (dry) and boat should be around 400-500lbs of tongue weight. That puts me at 4600-4700 dry. 40 gallons of water (dont have to always be full) at 320 lbs, im 190lbs, wife is 100lbs, and two small girls at 60lbs for both.. gear and other crap would put me at around 5300-5400. Should i get a semi? lol shoot, i went to look at an F450 (please dont ban me from this site) and the payload was 4600lbs!! So, i am this factory airbag thing might be a deal breaker. I don't know...
By no means i am a speed demon, and I dont think i'm towing a lot, lets say 5200 of payload, and 5000lbs boat (might upgrade to a tad heavier boat in a few years). I've read there is no big difference between 4.10 and 3.73s, am I wrong?
I am looking at a 2019, not even an option for 50 gallon tank.
I'm getting rolling with the truck now because finally found the almost same exact thing options i had on the SRW (2019 instead of 2020, different leather color, and 4.10s) in a DRW for a very good price in my opinion....
Just throwing my 2 cents worth in even though it ain't worth but a penny at most. I love my drw with factory air suspension. I got the 410 gear and I'm a spd demon. When I'm hauling 13k i get around 9-11 as an average and without trailer average around 12-15. My understanding was that first tractor gear was the only difference between between the 410 & 373 and all the rest were the same, maybe I'm wrong. I like the 410 for the tq feeling out of the hole no matter the load weight. I personally owned the rfe tranny on my 2500 trade in and it did just fine but i wouldn't buy one now with out the aisin just for the capability difference. I didn't want to buy a truck that wasnt capable of every situation. I do realize everyone situations are different. Mine was to when i bought my trade in New in 2016. It had the rfe and 3 yrs later when i needed more capability, i then wished I'd bought the big rig from the get go as we all can understand and appreciate depreciation and resale values. We did do very well on trade value but your still throwing money away to buy new then get rid of it after a few years to buy new again. I'm not in to losing money. Drw 410 aisin all the way, no regrets, now anyway, just wish I'd made that decision long ago
F350 has a higher payload than the F450.

Thanks for the feedback, it pushes more towards the 4.10. Not sure if i mentioned, but the it does not have the AISIN, its the 68rfe with the 4.10s.. Any thoughts on that combo? The most i anticipate towing is the same camper and a 6500-7000 boat. I should be grossing at about 19-20k when that happens.
You will be more than good as long as it's the drw. I personally would wait for one with the HO Hd aisin tranny . 20k is allot of weight and even though based on specs the rfe is capable enough , i would want the extra hp and tq that comes from the Aisin tranny. Definitely want the 410 to get that weight rolling. I know its hard to anticipate what the future may hold but like with my situation, what was plenty good at the time, then life happened where we needed a bigger truck and I wish I had bought that from the beginning. I don't care how you cut it. When you pay 65k for a new truck then 3 yrs later trade it in for 35k, that cost you at least 30k for a 3yr truck, then buy an 85k truck, bad financial decision on my part, but Like I said we can't predict what the future holds, just make our best decision at the time. So here the max weight numbers based on the data.
6.7 crew cab 8ft bed 410 gear drw:
Rfe: gcwr: 30,300. Max trailer lbs: 21,680. PL: 5,850 hp 370. Tq: 850ftlbs
Aisin: gcwr: 43,000. Max trailer lbs: 34,110. PL: 5,590 hp: 400. Tq: 1000ftlbs
All these numbers are vehicle specific and are slightly different based on all the options yours has and it's specific vehicle weight.
So with your max haul being around 19-20k, you would be close to maxing out that rfe tranny but if its not a daily puller and just twice a month on short camping trips, you would be fine. If you ever upgrade to a bigger RV or hauling more often and more mileage than the rfe will not hold up like the aisin would as its capability is much greater.
My opinions are based on the facts that I have infront of me. Somebody else may have differing in formation that contradicts mine. In the end, you have to educate yourself and make your best decision for you based on your needs and remember all of our opinions, are just that. We don't pay your repair bills or your insurance claims if applicable, hopefully not.

Check out the gear splits here.
That's just the diff between 3.73 and 4.10 with the 68RFE gears.
The Aisin 1st gear is a lot deeper than the 68RFE so it's wise to go 4.10 with the 68RFE. The 6th gear OD

Push come to shove, the 68RFE is more "buildable" and tunable than the Aisin.
That said, it was my first choice after dealing with a 48RE behind a tune for years.
I don't know the size of the tires on the DRW, but here's a representation of the difference between each trans and rear gear ratio:
Again, the rfe is capable of a 21k trailer , any mods or tunes don't change the legal weights, just how it runs and everybody (not like myself) doesn't want to tune and tweek. J want it the most capable based on factory specs, wich is the aisin. Like i said, if your just occasionally towing 20k with the rfe for short miles, it will suffice. More weight and miles and occasions hauled, imop would require the aisin. We all have our opinions and understanding of the facts. Maybe you don't mind working on a brand new truck to gain more hp and tq, but my point is , why not just do it right the first time and get the big hp and tq rating so you don't possibly put your warranty In jeopardy. I mean for god sakes i can't even get ram to approve me using a k&n filter system or a dead pedal plug in corrector. Honestly I wouldn't give the rfe a second thought if you knew for a fact without a doubt that your weight limits would be down but thats exactly what i thought when i purchased my 2500 6.7 w/ rfe. I assumed 17k trailer weight capability would be plenty, but life changed and it wasnt . Just like everything else with a weight rating, you buy more than what you need so your not maxing out the equipment wich can lead to a failure. Only you know what's best for you. Happy hunting, thats part of the excitement, finding the perfect one

I gotcha, thanks for the feedback. I have a smaller tacoma I use for daily driving so most miles on the dually will be towing.. There is this steep grade near the lake I frequently camp at, so I am looking at it as more than occasional towing. Happy to be here and be learning from you guys.
I noticed a 260 lbs less payload with the AISIN, is it really that much heavier or were other options included? I must say, you're starting to sell me on AISIN..
I'm stalling the deal I currently have right now (18k off MSRP) and considering ordering new with those options

Yup... I'm the same way, I don't tweak or tune things involving any parts of the powertrain.. little mods here and there to make it to taste sure, but don't mess with stuff that may void factory.
You seem to easily take personal offense at someone stating a simple fact. Lighten up Francis.
