    What are your thoughts on a 2018 2500 diesel vs. a 2019 2500 diesel?

    Both new.

    Any pro's or con's for either?

    2018 last year of its kind. Can get a manual if that's your thing. Of course it depends on the deal and how badly they want to sell something, I'd imagine deals on 2018 are going to be generally better especially this late in 2019. Aftermarket support is well established.

    2019 first of its kind. I think there are a lot of improvements with the new trucks inside and out. However any 1st year vehicle could definitely have its quirks. Same cab/bed as 2018 with a refreshed front clip, taillights, and interior. Is the HD going to get the new cab in 2020 or 2021, making the 2019 HD a bastard oddball year? Time will tell but I'd imagine they want to combine their tooling costs sooner.

    Unless you're buying the max tow 3500 with the HO/Aisin for 1000 lb-ft, or absolutely need a lot of the fancy new stuff available in the 2019, a 2018 is probably better for the wallet and all. It depends if the luxury stuff is a "gotta have" for you, or if you're like me and are perfectly happy driving a base model.

    I would either buy an 18 to avoid the new engine design and potential issues associated with it or wait and see when the cummins 8 speed debuts.

    Dad has an '18 3500 srw and has been great so far.

    I just looked at an 18 and a 19 side by side. The 19's interior was brand new, it even had the 12" screen.

    The 18 was the good old familiar truck that I already know. And, without any prompting, the dealer was knocking 12K off the sticker.

    Now the salesman said the engine and drive line was the same. Is that true? I thought the 19's had the new engine and same 6 speed?

    I believe the 19 gets the updated engine (cgi block, new head, new internals, etc) but it's downrated to 850lbft (compared to the max 1000lbft available in the 3500). I dont know if they had to update the 68rfe to handle the extra torque (2018 is 800lbft). this combination is also offered in the 3500 in addition to the 1000lbft/aisin combination.

    Personally, i prefer the interior and exterior of the 18. with that, and the uncertainty of new untested components, I would not even consider the 19.

    I would fire whoever was in charge of the 2019 redesigns for both the 1500 and HDs, it's not that they are ugly (still better looking than any of the competition imho) but the new looks are a step backward compared to the 2018s

    The '19 has a near totally new engine from block construction to near all internal parts and turbo. It is designed to be both stronger and more fuel efficient. Of course the stupid thing on that last issue is they dropped the 3:43 rear end ratio so the most (least) fuel efficient rear-end ration available.e is 3:73. Absolutely stupid in my book.

    Next on the '19 there is a slight revision with the automatic transmission, the only transmission available. It 's basically the same 68RE six- speed with a few changes to handle the extra torque and make the linkage shift more reliably.

    I would be ecstatic were it not for that rear-end ration issue. For those running speeds below 70 mph and tow above say 14,000 lbs, the 2019 is the logical choice. If you tow light and run interstate speeds upwards of 75 mph, read more and figure out what the fuel penalty will be at those speeds with the "supposedly" more fuel efficient engine.

    Wait and see what they did with transmission ratios before you condemn their rear end ratio. Drove around on our ranch all weekend. In my ecodiesel I limit the top gear to 2nd and at 10 mph run about 1500 rpm around the pasture.

    In the old man's '18 cummins with 3.42 gears it ran 1st gear the whole time at 10 mph and 1200 rpm. 500 mile round trip the cummins with about 5000 lbs trailer on the way down and trailer with a pick nick table and some other stuff on the way back was a little better than 16 mpg average.

    Top ration on the 68RE transmission for 2019 is the same. Forget the number but something like .6:1. Now in the future the 8 speed ZF may reduce that to say .5 or even .4:1. That would effectively drop the final gearing using the 3:73 rears. Then you can run 70 mph under 1,800 rpm.

    Friend with a 2017 Cummins called me Saturday to tell me that at 70 mph he is tacking something like 1,600 rpm. 3:42 rears is what I told him he had. He also has larger tires so just my guess and I do not remember his exact numbers right now.

    The whole issue is not about crawling around a field. It is about normal operation by ME. I really would like to run 75-80 mph at rpm/s UNDER 2,000. Sure do that now with my Ecodiesel and get 28 mpg at those speeds. Get even more at lower speeds and rpm's. You put a Cummins on the road at 2,000 rpm or more and the fuel mileage tanks.

    It would be "pound foolish" to have a vehicle yielding lower fuel mileage at the speeds they normally run. Now that's only an issue if you have a limited income. Unfortunately, I do. Fuel costs are a major issue related to what I can buy and how I normally use my vehicles.

    Just food for thought Capt. Our 5,000 lb boat that has little wind drag compared to a box camper makes the 2018 3.42 geared cummins hunt for gears bad enough that we tow with it in 5th gear. And that is in the lowly flat lands of south texas.

    Captainmal, I see your predicament. My 3.42 gears are a decent compromise. I can loaf down the highway above idle, next to no boost but can lock out gears when towing to keep it in the sweet spot. I found that I do not need numerically high rear end gears at all to tow the loads I do. The AS69RC has a stupid deep first gear and the ISB6.7 has so much torque off the line. For what you tow, you have no need for anything but the 3.42.

    What one needs to do (One day I hope to) is do some hand calculations for unloaded highway driving while in 6th and in 5th. According to my lie O'meter, it shows little to no difference but again, hand calcs is where it is at.

    Now what some guys have done is gear swaps. But this seems to be the guy that requires a SRW but needs absolute max tow or the guy with ridiculously large wheel/tire combos. For guys like us, any gains you might get in a gear swap are never realized monetarily over the cost of the swap.
