First long tow with my 7.3 Tremor, truck did very well. Towed my 392 Rubicon to Uwharrie National Forest and back for some rock crawling. I live in Eastern NC where it’s flat as a pancake. Uwharrie is an hour and a half southwest of Raleigh, NC. So a lot of the drive is the rolling hills of the Piedmont. No huge passes but plenty of up and down. About 220 miles one way from my house.
Previous truck is a deleted 2014 Ford F250 6.7. Ran a mild tow tune on it. I would average about 10.5MPG towing the same load. That’s running 70ish for a good portion of the trip and 60-65 everywhere else.
The 7.3 has plenty of power to tow the trailer with confidence. Was in 10th gear in all of the flat sections of 70mph zones. On a couple of grades the truck was definitely working, had it down to 5th gear/4K RPM when accelerating uphill in some spots but most of the steeper hills were pulled in 7th @ 3K RPM or 8th @ 2.5K RPM. On the drive to Uwharrie I tried to lock out gears ahead of the hills to get it into the powerband early but on the drive home being tired and lazy I just let the truck do its thing with the cruise control on. It would lose 2mph then downshift from 10th to 8th. If needed it would downshift again from 8th to 6th. Worked just fine.
Averaged 8.1MPG for the trip, fuel costs between my old truck and new truck for the trip are a wash. Very pleased with that! The 7.3 sounds very good under load
I’ll be leaving the exhaust stock though, lots of towing in this things future. Was nervous about not going diesel this time but I’m good with my decision now. I do wish the 48 gallon gas tank was an option on short bed trucks! If someone gets the DTE issue figured out on the 23’/24’ trucks I may buy the TransferFlow 58 gallon tank. Until then though I’ll deal with the 225-250 mile towing range 
Trailer is 4K pounds (20’ PJ F8 14K Deckover) and the Jeep is right around 7K pounds with the one ton axles & 40s. So 11K combined. Burned 87 octane for this trip.
