I've had a 2017 F-250 & 2019 F-350; both 6.7's. My 17 was a F-250 Platinum and had horrible body gaps including a door that was denting the inside bottom below the interior trim and that was probably due to being the first year of the new aluminum body style. My 19' was a Lariat F-350 which had no problems at all, great truck. Both of these were used at works trucks, my main day to day complaint was the overall height and loading/unloading. The Ford's look great and have a ton of power but still look like the skipped leg day.
Payload does need to be increased in the Ram 2500 IMO. This will make my 4th Cummins since 2017 and maybe this will sway your decision but my last Cummins (2018) caught on fire in my driveway with only 7,000 miles. I swore I would never buy another Ram however IMO Ford has too many irons in the fire between bringing more types of vehicles to the market, quality control and reducing costs. I don't think a customer should have to spend $125 for a garage door opener on a truck that has a MSRP of over $65,000. Ford no longer paints under the hood, inside the top of the fenders or firewall to "save money." I also dislike the fact that you must order a Lariat trim to have black interior; I would rather have cloth. Ram has considerably upgraded interiors and again this is in my opinion based on my friend's TRX that the fit, finish and quality of the leather seats with equal to those in a Porsche.
My 2021 F-250 7.3 Tremor had two cracked tail lights at 430 miles, had to fight Ford to warranty them at $730 a light without the electronics that had to be swapped these were LED and sensor type lights; but the dealer ended up taking care of it. At 6,600 miles the ECM went out. I wasn't going to wait on a replacement so I bought an 2020 F-150 3.5L Ecoboost off the lot (no problems in 11,000 miles and 3 months of ownership. Swapped to a 2021 F-150 5.0 and I get random alerts like "Reverse Brake Assist Not Available, See Manual" the new shifter occasionally acts up since it puts the truck into park automatically if a door gets opened and you have it in drive or reverse. The new single leaf rear suspension is the worst I've ever experienced and bounces like no other. I bought my wife a 2020 Explorer ST and with 23,XXX miles its had over 8 TSB's/Recalls; leather in the seats come untucked from the bottom, trim panels chaffing, now it sounds like what Ford calls Cam Phasers are having issues and cold starts are....interesting. It will be gone soon too.
If you want more power & acceleration go for Ford, If you want overall reliability then I would go with the Ram. The 10 speed transmissions will have problems after 50k + miles if used for towing. I've also had a 2020 Chevy Duramax 3500....just nope to that to throw that in there.
