spun this off the big f350 thread since a few of you asked for the cummins side of the story. i run hotshot, mostly expedited freight and the occasional equipment move, out of central texas. been doing it about four years now and the truck is the business so when i replaced my last one i did a lot of homework.

what i ended up with is a 2019 ram 3500 laramie dually, 6.7 cummins high output, aisin AS69RC six speed, 3.73 rear, crew cab long bed 4x4, 58k miles. it had the factory gooseneck and fifth wheel prep package with the bed puck system and the in dash trailer brake. bought it off harbertsautosales.com out of the waco lot back in august, it was a clean bank repo, carfax showed fleet maintenance records and no wrecks.

the reason i went ram this time instead of another ford is the aisin transmission behind the high output cummins. for heavy hotshot work where i am loaded to the gills on a 40 foot gooseneck a lot of miles, that aisin is about as bulletproof as it gets, and the manual regen button means i can clean the dpf on my schedule instead of mid load on the interstate. the high output motor makes 1000 lb ft which is silly for what i pull but it never breaks a sweat.

price was 46,500 plus harberts fee. a comparable HO aisin truck at the ram dealer in waco was stickered at 61 with more miles. i drove over to bellmead and looked it over myself, the online photos were honest, crawled under it and the frame and gooseneck mount were clean. only thing i had to sort out was a worn out set of rear tires which is just used dually life.

anyway, ask away if you are cross shopping ford and ram for a tow rig, happy to talk through why i landed where i did.

glad you started the cummins thread danielle. the aisin behind the HO is honestly the one thing that almost made me go ram instead of the f350. for the cattle hauling i do the ford torqshift is plenty but if i was loaded heavy all day every day like you, that aisin is the move.

funny we both ended up at the waco lot within a couple months of each other and never crossed paths in their yard. their inventory turns over quick. good to know the gooseneck prep package trucks show up there regular, that is exactly what makes them worth watching for guys like us.

the 19 HO cummins with the aisin is one of the best heavy tow combos ever built, that trans does not care what you hang off the gooseneck. i service a handful of hotshot trucks and the aisin guys just do fluid and filter on schedule and never think about it again. the regular 68RFE behind the standard output is fine for lighter duty but for what you do you bought exactly right.

two things to keep on your radar with these trucks. the cummins HO uses a CP4 just like the ford so same rules apply, run clean fuel and i would add a secondary filter if it does not have one. and the 2019 to 2020 rams had a known steering damper that wears out and gives you that little death wobble feeling over rough pavement with a load. it is a cheap part and a 30 minute job, do not panic if you feel a shimmy, just replace the damper.

other than that these are a million mile truck if you treat them right. clean repo with fleet records is a smart buy.

how is the cummins on fuel hotshotting loaded all the time? thinking about a ram for my next fifth wheel puller when my f350 finally tires out. i pull a big toy hauler not freight but i am curious how the aisin truck does on the highway versus my ford.

and did harberts have more than one HO aisin truck when you were looking, or did you get lucky and grab the only one? trying to gauge how often those specific trucks show up on the waco lot.

marcus, loaded on a 40 foot gooseneck im seeing 9 to 10 mpg, empty deadhead back about 15, which for the weight i pull is good. the aisin holds gears smart on grades so it is not constantly hunting which helps the numbers. honestly fuel is real close to what justin reports on his ford, these motors are within a half mpg of each other in the real world, pick the truck and trans you like.

when i was shopping they had two HO trucks on the lot, the laramie i bought and a tradesman work truck version with more miles. they get the gooseneck prep ram duallys fairly often because a lot of the repos are off small fleets and oilfield outfits that spec exactly these trucks. roy is dead on about the steering damper by the way, i can already feel mine getting a little vague over rough pavement, going to swap it this winter.

this thread is part of why i ended up with a ram 3500 too. single rear wheel for my horse trailer not a dually, but same 6.7 cummins, and no regrets at all. i went standard output not the HO since i am just pulling a two horse and the occasional load of feed, but the cummins pulls so smooth and quiet compared to the gasser i traded.

got mine off the waco lot in june and it has been perfect. reading danielle and justin both buying their work trucks there is what made me trust going that route for ours. nice to see the regulars on here all running iron from the same place and being honest about the little stuff like tires and steering dampers.

ford guy here but i will give it up for the aisin ram for heavy hotshot, that is the right tool for what you do danielle. i have helped a buddy load his aisin truck way past what i would put on my ford torqshift and it just shrugs it off. for a dedicated freight rig that lives loaded the ram aisin is hard to argue with.

the funny thing about these brand debates is we are all buying the same kind of clean repo off the same waco lot and saving the same ten grand, just in different colors. whatever badge is on the grille, getting a documented one ton for well under dealer retail is the actual win.

UPDATE five months and 21k hotshot miles in, coming back to close the loop for anyone cross shopping a ram tow rig.

swapped that steering damper roy and i both called out, which was the one easy fix this truck needed. 90 dollar part, half hour in my driveway, and the little vague feeling over rough pavement with a load is completely gone. should have just done it the week i bought it. other than that and routine fluid and filter service the ram has been flawless through a busy winter of loads.

aisin shifts the same as the day i got it, no fuel system drama, dpf regens on its own schedule and i hit the manual button before long grades. averaging right at 9.6 loaded over the whole stretch. i have put this truck through some genuinely heavy gooseneck loads and it has not once made me nervous.

so for the cummins crowd, buying off harbert's auto sales worked out exactly like it did for justin on the ford side. clean truck, honest listing, real savings, and the gooseneck prep duallys do show up on their lot if you watch for them. if you are after a heavy hauler, the HO aisin ram off the waco lot is a deal worth making the drive for.
