7.3 or/vs 6.7
My solution to the 34 gal fuel tank in my 7.3 Supercab is to buy a new Crewcab long bed with the 48 gal fuel tank.
I'm looking at a 7.3 Lariat F350 with a bunch of options that are nice but not really needed or a F250 6.7 Lariat and no other options.
Both trucks are 2wd, long bed Crewcabs. I don't need a 4x4 and I prefer the front suspension and lower height of the 2x4.
They price difference is $1000 OTD.
I bought my Supercab heavily discounted and trade in is slightly more than I paid OTD, so no money lost there.
The 7.3 has dual alternations/batteries, uofitter switches, 5th wheel prep, spray in liner, power boards and a tailgate step. The 6.7 doesn't have anything beyond the Lariat trim.
Opinions?

Guess it comes down to how you will use the truck.
Personally I would stay away from diesel unless I needed it for heavy loads and long distances.
I was not aware you could delete 4x4 from anything above XL level. I know it was standard equipment in XLT and above in '24. There might have been a delete option that I'm not recalling.

If it is mostly a daily driver with occasional heavy towing, you might want to lean more heavily toward the 7.3. Mileage is going to be worse (I'm averaging 21+ even with my Tremor package, some guys with the diesel get considerably higher, while the 7.3 comes in closer to 15-18 depending on driving conditions), but you get cheaper fuel, cheaper oil changes, and less potential mechanical issues down the road. You also get a higher payload with the gasser in MOST configurations.
Like I said, it comes down to your usage. My situation lends itself to a diesel (I'm either putting a lot of miles on and need the range, OR I've got a trailer of some kind behind me), otherwise I'd have a 7.3 despite the worse mileage.

We tow a 8000# travel trailer all over. The 8.5-ish mpg sucks, I would expect the diesel to get slightly better.
My 25 Supercab 4x4 is a great truck, but the misses likes the Lariat trim and I want the big fuel tank. 2-3 fuel stops a day gets old fast.
I think that I am going with the 7.3. I like the Marsh Gray and although the 6.7 will pull better, we are in no hurry.

Off the top of my head, if I were to subtract the options you've listed on the F-350, The f-250s would be approximately $6,000 more, but if you can get it for $1,000 difference, that's a no-brainer for me.
You'll get better fuel economy, distance between refuels, but with diesel being roughly a dollar higher that part might be a wash. For me, for towing is the range very important.
I would first look at a gasoline transfer tank to put in the bed if your current truck is satisfactory for what you're trying to do.
