Seeking advice on a SD
6.7HO without towing does not burn DEF. I don't even think I've used 10% of it yet...and I've put nearly 1000 miles on mine since I bought it. 5th Gen really does lean into DEF as an alternative for EGR. I haven't ever seen the metrics on EGR use/percentage for 5th gen, but if you're reducing/eliminating it and using DEF to compensate--that would make sense. I've seen 1 regen cycle, and it was totally seamless and i didn't even see a notification for it happening; just watched the DPF filter dropping %.
I agree that if you're not towing as much, the 7.3L gasser makes more sense. I never seriously considered it, because 1. Gasser isn't an option on the F450 and 2. No gasser has a rating for a 22k GVWR trailer. So even though I'm driving unloaded 100% of the time currently--that's not how it will remain in the future. Same reason I'd go with a CCSB like you test drove, instead of a RCLB or CCLB. LB makes sense if you're pulling a big trailer. Not so much if you're used to the limits of an Excursion's towing capabilities--because you wouldn't need the extra length. And LB other than the F450 is a PITA to maneuver.
58k miles is barely even broken in--as far as a PowerStroke is concerned.
I'll have updates to my thread on 5th gen year-to-year changes...hopefully this weekend. That'd be the best place to identify the "sweet-spot" on features you want. Mine was tailgate camera and backup sensors (2024 was the last year). 100% Lariat as a minimum would be my recommendation. There's just too many "have to check that option box" on the XL/XLT to ever recommend them. I love my Limited, and I didn't want the hassle of trying to determine if a lightly used one had all of the features I wanted--so I opted for the Limited. Barely cost any more than a Platinum of the same year/mileage. And new wasn't an option in 2026--since I wanted those tailgate features.
I started looking into a SD about 2 years ago. I initially set 4th gen as my "minimum" (wife REALLY wanted White Gold). When I started looking into it more, I set 2020 as my "mimimum", as I really wanted the efficiency of the 10 speed. At that point, I might as well just go with the HO engine and the features upgrades for the 5th gen--so 2023 became my "desired minimum". And because I'd done a lot of research about 5th wheel RV towing, I decided that the 450 was the ticket. And buying those new--is kind of a PITA it would seem. So I found a Quebec/Habs special (SD sold in Canada, used, and then resold back into the USA). Something with ~7,000 miles. So pretty minty. And I'll hopefully keep it for years to come.
For you, based on everything you said, I stick to what I posted above. 7.3 Godzilla. CCSB. Lariat or higher. And you can probably find a solid deal on a 2026 as the 2027's are about to start rolling out. 250's are going to be far easier to come by (even 350's).

I have been a member of the FTE for 10+years now, and have spent all this time driving Excursions - 7.3, 6.0 and now a v10. I am looking to switch over to something more modern with tech and creature comforts. My usage of these trucks are 90% is a people mover, I like to drive them big trucks, and 10% for the reason they were built that way. IYKYK

I've been searching for 2020+ (preferably) F250 with the 6.7. Lariat or higher trim. I took a '24 F250 with the Lariat Ultimate trim and 10 speed for a spin. This was the first time I have drive a 6.7, and I was completely floored by the truck. The only downside I could find with this truck was that it already has 58K miles which means the 3/36 warranty has expired, and the 5/60 warranty is almost gone.
While I am fairly familiar with the 4R100/5R110 transmission on the Excursions, I have no experience/knowledge of the 6 and 10 speed transmissions on the newer trucks. I was chatting with another senior FTE forum member a couple of days ago, and he suggested that I should be looking at the 2017-19 model years with the 6 speed as they are more proven than the 10 speed. I am looking for advice on which one to pick. Pros/cons of each.
Then comes the DEF story. I have generally heard and read about the good and bad of DEF and impacts on the emissions systems. I'd say the opinions are generally split 50-50. But, what do y'all collectively think about this.
As a rookie with pickups in general, and the 6.7 in particular, what should I watch for when buying one?
TIA. PFA of the truck that I test drove.
If you can wait 6 months, I've got a pristine '22 Platinum that'll be available.
I just picked up a new 6.7 HO 3.55 F350 and it is awesome no doubt, BUT seriously my 7.3 truck with 4.30 is more fun to drive around. Its just different, it's sportier, lighter and sounds better. The 6.7's are cool in their own way, pulling trailers on grades is #1 on it's "pro" list to help offset the few extra on its cons side of the list.
Can't go wrong with either though I always side with newer and warrantied- especially diesels. They aren't all going to explode like some people think but a $8-12k repair bill would upset me to no end
My last "new" vehicle purchase was in 2003, and I swore never to buy another brand new one and take the hit on the depreciation. I just can't afford to lose all those $$.

Towing with the 6.7 is ok with the 34 gallon tank, acceptable. Not with the gas though. That is a crew cab short bed tank size.
If you do a 5th wheel you will want a 350 or high capacity f250 if you find one you like (air up the tires to 80).
Long bed crew cab gets you a 48 gallon tank.
The pic of the truck you test drove looks like a bro wagon lift, not something that will tow or work.

With your having owned three Excursions now, and my having followed your journeys with each of them over the years, I'd like to suggest that you combine any planned for outdoor summer chores in your new place with a pickup truck rental from Enterprise.

Much can be learned by having the truck to yourself, at your home, in your neighborhood, on your routes, doing your business (or recreation), without a salesperson present, and without fear of damaging the dealer's inventory, and without being short circuited on test drive time.
With a truck rental, you can self-resolve questions about the compromises of vehicle length, vs fuel capacity, vs tow porpoising, vs parking situations, vs ride comfort, etc.
Sure, a rental adds a significant expense to the vehicle acquisition/transition cost, but the rental expense is substantially less than the whipsaw of depreciation after a discovery through use that the wrong size truck was purchased before adequate auditioning, which must then be traded in for the right size truck.
Just hitting the basics but I bet if he is serious about buying a 5th wheel and also using this as a daily driver he will end up in a crew cab long bed F350 6.7 4x4.
I actually have a 2025 like that in King Ranch HO 6.7 I am going to sell soon. 14k miles.
